AN8013SH Single-channel step-up or step-down DC-DC converter control IC

Unit: mm

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.
