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 device uses pulse-widthmodulation (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 dualbattery designs. The HPW7095/A incorporates error amplifiers, output short-circuit detection, under-voltage lockout, soft-start and output switch control into a chip. The HP7095/A improves performance, component count, and size compared to conventional multichannel controllers.

The HPW7095/A has a power-good indicator (PGOOD) that signals when CH1 output is within ±10% of the set voltage by monitoring IN1 pin.

The HPW7095/A is available in compact 48-pin plastic LQFP and TQFN packages.
