Product Descriptions
The AP65355 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.
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.
DCM allows AP65355 to maintain high efficiency at light load conditions. The AP65355 also features power good, programmable soft-start, UVLO, OTP, OVP and OCP to protect the circuit.
This IC is available in U-DFN3030-10 package.
