PIP250M
Integrated buck converter
Rev. 02 — 21 February 2003 Product data
M3D797
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, efficient design with minimal external component count.
2. Features
Output current up to 15 A
Single supply 5 V operation
Fixed 300 kHz operating frequency
Voltage mode control
Minimum regulated output voltage 0.8 V
Internal soft start
Overcurrent protection
Overvoltage protection
Remote sensing.
3. Applications
High-current point-of-load regulation
Distributed power architectures
