Product data
1. Description
The PIP250M is a fully integrated synchronous buck converter intended for use as a
point-of-load regulator. It contains two N-channel power MOSFETs, a Schottky diode
and a voltage mode, pulse width modulated (PWM) controller. The controller features
include overcurrent and overvoltage protection and undervoltage lockout functions.
By combining the power components and the controller into a single component,
stray inductances are virtually eliminated, resulting in lower switching losses and a
compact, ef鏗乧ient design with minimal external component count.
