BP5250, 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 recom

DC/DC converter BP5250/BP5250-24 The BP5250/BP5250-24 are DC/DC converters for step-down that can drive PchFET using PWM system.

The voltage setting resistor and the combination of external power elements enable you to make any power circuit to your liking.

High-efficient DC/DC converter can be made easy by adding external components such as I/O smoothing capacitor without designing circuit.

Applications OA appliances(copy machine,personal computer, facsimile), AV appliances (car navigation, DVD

BP5250 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 (Dete
