Diodes' AP65355 / AP65455 are adaptive constant on-time (aCOT) mode synchronous buck converters providing high-efficiency, excellent transient response, and high DC-output accuracy for voltage regulation in digital TVs and monitors.
The aCOT control scheme handles wide input/output voltage ratios and provides a low external component count. The AP65355 / AP65455 supports a seamless transition between continuous conduction mode (CCM) at higher load conditions and discontinuous conduction mode (DCM) at lighter-load conditions for high efficiency.
The AP65355 / AP65455 operates at a fixed 650 KHz to achieve good output stability. These devices also feature programmable soft-start, UVLO, OTP, high-voltage tolerance EN Pin and OCP to protect the circuit. The AP65355 / AP65455 are available in DFN3030-10.
