HPW7095/A

6-Channel DC/DC Converter Control IC

Features

General Description

The HPW7095/A is a 6-channel, frequency-settable,

voltage-mode, DC/DC control IC providing a complete

power supply solution for high-performance portable

digital cameras. The HPW7095/A uses pulse-width-

modulation (PWM) and synchronous rectification for

high efficiency step-up, step-down, up-down and in-

verting converters with free input and output settings

in 2 or 4-cell AA, 1-cell lithium-ion (Li+), and dual-

battery designs. The HPW7095/A incorporates error

amplifiers, output short-circuit detection, under-volt-

age lockout, soft-start and output switch control into

a chip. The HP7095/Aimproves performance, compo-

nent count, and size compared to conventional multi-

channel controllers.
