General Description
The APW7095/A is a 6-channel, frequency-settable, volt-
age-mode, DC/DC control IC providing a complete power
supply solution for high-performance portable digital
cameras. The APW7095/A uses pulse-width-modulation
(PWM) and synchronous rectification for high efficiency
step-up, step-down, up-down, and inverting converters
with free input and output settings 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-voltage lockout, soft-start, and output
switch control into a chip. The AP7095/A improves
performance, component 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
±10%
of the set
voltage by monitoring IN1 pin.
The APW7095/A is available in compact 48-pin plastic
LQFP and TQFN packages.

are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
