APW7095A

APW7095/A 6-Channel DC/DC Converter Control IC Features www.DataSheet4U.com General Description The APW7095/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 APW7095/A 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 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 multichannel 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. Supports for synchronous rectification (CH1, CH2 and CH5) Supports for down or up-down Zeta conversions (CH1 and APW7095 CH2) Supports for up, flyback or up-down SEPIC conversions (APW7095A CH2, CH3, APW7095 CH4, CH5 and CH6) Supports for Inverting conversion (APW7095A CH4) Low Start-up Voltage : 1.4V (CH6) Power Supply Voltage Range - CH1 to CH5 : 3.0V to 6.5V - CH6 : 2.4V to 6.5V 1% Reference Voltage Accuracy Wide Operating Frequency 100kHz to 1MHz Soft-Start Fu...
