AP65352 - Diodes

AP65352 650kHz ADAPTIVE COT STEP-DOWN CONVERTER

The AP65352 is an adaptive, constant on-time mode synchronous buck converter providing high efficiency, excellent transient response and high DC output accuracy for low-voltage regulation in digital TVs and monitors. Pin Assignments ( Top View ) The constant-on-time control scheme handles wide input/output voltage ratios and provides low external component.

Features

programmable soft-start, UVLO, OTP, OVP and OCP to protect the circuit. AP65352 operates in continuous conduction mode (CCM) in light load conditions for better EMI performance. AP65353 and AP65355 are the options for light-load efficiency enhancement. EN 1 FB 2 VREG5 3 SS 4 Exposed Pad 9 SO-8EP 8 VIN 7 BST 6 SW 5 PGND This IC is available in SO-8EP package. Features
