BQ2471X SMBus Controlled NVDC-1 Charge Controller Visualizar Arquivo The bq2471x evaluation module (EVM) is an SMBus controlled NVDC-1 charge controller with N-CH MOSFET selector and current monitoring. The input voltage range, for the buck converter, is between 6 and 24 V, with a programmable output of 2–3 cells (bq24715) and 3–4 cells (bq24717) and charge output current range of 128 mA to 8.128 A. This EVM doesn’t include the EV2400 interface device (HPA500); this must be ordered separately to evaluate the bq2471x EVM. Uploader Carlos Porto Enviado 11-06-2021 Categoria Datasheets -
doc APW8723 5V to 12V Single Buck Voltage Mode PWM Controller
Carlos Porto postou um tópico em Gerenciador de arquivos
APW8723 5V to 12V Single Buck Voltage Mode PWM Controller Visualizar Arquivo The APW8723 is a voltage mode, fixed 300kHz switching frequency, synchronous buck converter. The APW8723 allows wide input voltage that is either a single 5V~12V or two supply voltage(s) for various applications. The power-on-reset (POR) circuit monitors the VCC supply voltage to prevent wrong logic controls. A built-in soft-start circuit prevents the output voltages from overshoot as well as limits the input current. An internal 0.8V temperature-compensated reference voltage with high accuracy is designed to meet the requirement of low output voltage applications. The APW8723 provides excellent output voltage regulations against load current variation. APW8723 is built in reference voltage offset function for applications that require adjusting supply voltage. The controller’s over-current protection monitors the output current by using the voltage drop across the RDS(ON) of low-side MOSFET, eliminating the need for a current sensing resistor that features high efficiency and low cost. In addition, the APW8723 also integrates excellent protection functions, The over-voltage protection (OVP) , undervoltage protection (UVP) and over-temperature protection (OTP). OVP circuit which monitors the FB voltage to prevent the PWM output from over voltage, and UVP circuit which monitors the FB voltage to prevent the PWM output from under voltage or short circuit. OTP circuit which monitors the junction temperature to prevent over-heating conditions. The APW8723 is available in TDFN3x3-10 package. Uploader Carlos Porto Enviado 08-06-2021 Categoria Datasheets -

High Efficiency, Main Power Supplyfor Notebook Computer The RT8205L/M is a dual step-down, switch mode power supply controller generating logic-supply voltages in battery powered systems. It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and also features fixed 5V/3.3V linear regulators. Each linear regulator provides up to 100mA output current with automatic linear regulator bootstrapping to the PWM outputs. An optional external charge pump can be monitored through SECFB (RT8205M). The RT8205L/M includes on-board power up sequencing, a power good output, internal soft-start, and internal soft-discharge output that prevents negative voltage during shutdown. The constant on-time PWM control scheme operates without sense resistors and provides 100ns response to load transient response while maintaining nearly constant switching frequency. To eliminate noise in audio applications, an ultrasonic mode is included, which maintains the switching frequency above 25kHz. Moreover, the diode-emulation mode maximizes efficiency for light load applications. The RT8205L/M is available in a WQFN-24L 4x4 package. -

1 to 4Cell Hybrid Power Boost Mode Battery Charge Controller With Power and Processor Hot Monitoring The bq24780S device is a high-efficiency, synchronous battery charger, offering low component count for space-constrained, multi-chemistry battery charging applications. The bq24780S device supports hybrid power boost mode (previously called "turbo boost mode"). It allows battery discharge energy to system when system power demand is temporarily higher than adapter maximum power level. Therefore, adapter does not crash. The bq24780S device uses two charge pumps to separately drive N-channel MOSFETs (ACFET, RBFET, and BATFET) for automatic system power source selection. Through SMBus, system power management microcontroller programs input current, charge current, discharge current, and charge voltage DACs with high regulation accuracies. The bq24780S device monitors adapter current (IADP), battery discharge current (IDCHG), and system power (PMON) for host to throttle back CPU speed or reduce system power when needed. The bq24780S device charges 1-, 2-, 3-, or 4-series Li+ cells. -

em análise Teclado controlador / akai / mpk 61 usb midi keyboard controller /preciso do Manual eletrico
Linkcellaju postou um tópico em Eletrônica em Geral
Bom dia, Estou com um teclado musical akai mpk61, problema dele a alguns anos sem conhecimento algum resolvi abrir pra limpar e trocar o potenciômetro do pith bande do mesmo, notei que alguns botões dos registros estavam ruim e que em tese seria fácil fazer a troca, de uma certa maneira foi mas ao montar ou no manuseio fiz algo errado que quando liguei o visou e as funçoes ficaram doidas as notas do teclado umas funcionavam outras não o visor ficou doido, hoje com um pouqui de experiência e por não encontrar um eletrônico que pegue esse tipo de teclado para fazer esse reparo, vou tentar fazer pra não perder de vez meu instrumento que suei sangue literalmente pra conseguir. Se alguem puder me dar um norte e conseguir esse esquema eletrico ficarei muito Grato. Deus no comando sempre

Ola então quero substituir o componente GS72v3 pelo Up1542s q e oque tenho disponível pois quase não acho o GS72V3 na internet alguém me ajuda , ou pelo menos me diz se existe algum equivalente para ele..!!

Boa tarde pessoal! Estou com um controlador de bomba de água, que aparentemente é utilizado em um poço, o controlador chegou sem funcionar mas ao abri-lo me deparei com uma situação complicada. Fusível aberto NTC fisicamente danificado Ponte retificadora em fuga e com um jumper de estanho entre o terminal negativo e entrada AC Diversas trilhas ausentes por conta da corrosão Um fio soldado para corrigir uma trilha corroída Botões de acionamento inadequados Possivelmente faltando alguns componentes Informações que pude verificar na carcaça do equipamento: OceanTech Professional Aquarium AC Pump Controller 220V / 60Hz 200W QC1801 Informações na PCB: XT106220W 170520 Minhas principais dúvidas: O jumper na ponte retificadora entre uma fase e o negativo é do projeto ou foi sacanagem de outro técnico? Na parte de cima da PCB é possível observar uma grande área com quatro pontos de solda, na parte de cima o sinal "+" e na parte de baixo o sinal "-", aparenta faltar um componente nesse local, pela serigrafia, acredito ser um capacitor, como são quatro pontos formando um quadrado, acredito que sejam dois capacitores de poliéster, mas esse tipo de capacitor não possui polarização, o que me deixa em dúvidas, eu arriscaria capacitores de 250v mas não tenho certeza sobre a capacitância. Alguém teria alguma informação ou sugestões? Obrigado a todos!
