For Automotive

BD8P250MUF-C

General Description

Key Specifications

BD8P250MUF-C is a synchronous rectification buck DC/DC

converter with a boost control function. This DC/DC

converter enables a common design that can meet a variety

of demands, including the use as a buck DC/DC converter if

a drop of the output voltage is acceptable during the input

voltage drop such as a cold cranking, and the use as a

buck-boost DC/DC with an exclusive boost-FET connected

if the output voltage must be maintained. The Quick Buck

Booster® technology realizes a high-speed response even

during buck-boost operations, allowing reduction in the

capacitance value of the output capacitor.

 Input Voltage A:

3.5 V to 36 V
