APW7095/A
6-Channel DC/DC Converter Control IC
Features
General Description
• Supports for synchronous rectification
The APW7095/A is a 6-channel, frequency-settable,
(CH1, CH2 and CH5)
voltage-mode, DC/DC control IC providing a complete

high efficiency step-up, step-down, up-down and in-
conversions (APW7095A CH2, CH3, APW7095 ^{verting converters with free input and output settings}
CH4, CH5 and CH6)
• Supports for Inverting conversion
in 2 or 4-cell AA, 1-cell lithium-ion (Li+), and dual-
battery designs. The APW7095/A incorporates error
amplifiers, output short-circuit detection, under-volt-
