HPW7095/A  
6-Channel DC/DC Converter Control IC  
Features  
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/Aimproves performance, compo-  
nent count, and size compared to conventional multi-  
channel controllers.  
Supports for synchronous rectification  
(CH1, CH2 and CH5)  
Supports for down or up-down Zeta conversions  
(CH1 and HPW7095 CH2)  
Supports for up, flyback or up-down SEPIC  
conversions HPW7095A CH2, CH3, APW7095  
CH4, CH5 and CH6)  
Supports for Inverting conversion (HPW7095A  
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  
TheAPW7095/Ahasapower-goodindicator(PGOOD)  
that signals when CH1 output is within ±10% of the  
set voltage by monitoring IN1 pin.  
1% Reference Voltage Accuracy  
Wide Operating Frequency 100kHz to 1MHz  
Soft-Start Function (CH1 to 6)  
The HPW7095/A is available in compact 48-pin plas-  
tic LQFP and TQFN packages.
