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/A improves performance, compo-
nent count, and size compared to conventional multi-
channel controllers.
The APW7095/A has a power-good indicator (PGOOD)
that signals when CH1 output is within
鹵10%
of the
set voltage by monitoring IN1 pin.
The HPW7095/A is available in compact 48-pin plas-
tic LQFP and TQFN packages.
