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 etc.),
and industrial appliances.
Features
1) High power conversion(
η
=90% Vin=12V 5V/2A)
2) Power save pin(Leakage current at OFF mode : IR=10
μ
AMAX)
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
