AN8014S
Step-down, step-up, or inverting DC-DC converter control IC
s
Overview
The AN8014S is a single-channel PWM DC-DC
converter control IC.
This IC can provide any one output type from
among step-down, step-up and inverting output.
Allowing n-channel power MOSFET direct driv-
ing, the AN8014S is ideal for high-efficiency power
supplies.
