BP5250-24 - Rohm

BP5250-24 DC/DC converter

Pin No. 1 2 3 4 5 6 7 Pin name VCTL Vi SW GND IS Vo VADJ Function Power save terminal.Setting the voltage on this terminal to Low or high impedance turns the output OFF. Normally connect to Vi for use. Input voltage terminal. Inserting a bypass capacitor of 0.1µF between this and pin 4 GND is recommended. Terminal to drive the external FET gate. GND termina.

Features

1) High power conversion(η=90% Vin=12V 5V/2A) 2) Power save pin(Leakage current at OFF mode : IR=10µAMAX) 3) Output voltage can be established from 1.5V to 9V in the VADJ pin.(For BP5250, however, output voltage is limted by input voltage.) 4) With recovery type overcurrent protection function (Detection current can be established by the external current detection resistance.) 5) Power circuit can be made easy by adding external smoothing capacitor and power element. 6) Reference voltage accuracy 1.25V±1% Absolute maximum ratings (Ta=25°C) Limits Parameter Input voltage ESD endurance Operating.
