FA7616CP(E)(V)
Bipolar IC
For Switching PowerFSAu7p6p1l6yCCPo(En)t(rVo)l
s Description
The FA7616CP(E)(V) is a bipolar control IC having two
channels of PWM-type switching regulator control circuits.
With this IC, a DC-to-DC converter can be easily implemented
for a minimum input voltage of 1.4V.
s Features
• Input voltage from 1.4V (VCC = 1.4 to 12V)
• Open-collector output
• Wide operating frequency range (fOSC: 10 to 500kHz)
• Output ON/OFF control function
• Not many external discrete components are needed
s Applications
• Battery power supply (two, 1.5V batteries) for portable
equipment

Parts tolerances characteristics are not defined in the circuit design
sample shown above. When designing an actual circuit for a product,
you must determine parts tolerances and characteristics for safe and
economical operation.
Please connect a capacitor, which the value is about 0.01µF to 0.1µF,
between VCC and REF terminals in order to prevent from irregular
output pulse at start-up.
