Overview
AP65455 4A, 18V, 650kHz ADAPTIVE COT STEP-DOWN CONVERTER Description The AP65455 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 TV and monitor.
Pin Assignments ( Top View ) The constant-on-time control scheme handles wide input/output voltage ratios and provides low external component count.
The internal proprietary circuit enables the device to adopt both low equivalent series resistance (ESR) output capacitors, such as SP-CAP or POSCAP and ultra-low ESR ceramic capacitors.
The adaptive on-time control supports seamless transition between continuous conduction mode (CCM) at higher load conditions and discontinuous conduction mode (DCM) at lighter load conditions.
EN 1 FB 2 VREG5 3 SS 4 PG 5 Exposed Pad 11 PGND 10 VIN 9 VIN 8 BST 7 SW 6 SW DCM allows AP65455 to maintain high efficiency at light load conditions.
The AP65455 also features power...
