AN8013SH
Single-channel step-up or step-down
DC-DC converter control IC
s Overview
The AN8013SH is a single-channel PWM DC-DC
converter control IC. This IC implements DC-DC con-
verters that provide a single arbitrary output voltage that
is either a stepped-up or stepped-down level. It features a
wide operating supply voltage range, low power, and a
built-in overcurrent protection circuit to protect the
switching transistor from damage or destruction. The
AN8013SH is provided in a 0.5 mm pitch 10-pin surface
mounting package and is optimal for use in miniature
high-efficiency portable power supplies.
