AP65353SP-13

AP65353 3A, 18V, 650kHz ADAPTIVE COT STEP-DOWN CONVERTER Description Pin Assignments The AP65353 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. ( 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. EN 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. 1 FB 2 VREG5 3 SS 4 DCM allows AP65353 to maintain high efficiency at light load conditions. The AP65353 also features programmable soft-start, UVLO, OTP, OVP and OCP to protect the circuit. Exposed Pad 9 8 VIN 7 BST 6 SW 5 PGND SO-8EP This IC is available in SO-8EP package.
