Diodes – AP65251 – 2A Adaptive COT Synchronous DC/DC Buck Converter
The AP65251 is an adaptive constant on-time (aCOT) mode synchronous buck converter providing high efficiency and excellent transient response. The AP65251 incorporates a control algorithm that improve efficiency at light loads.
The aCOT control scheme handles wide input to output voltage ratios and requires minimal external component count. The AP65251 could seamlessly transition between continuous conduction mode, CCM, at high loading and discontinuous conduction mode, DCM, when the inductor current is less than 0A for high efficiency.
The AP65251 switching frequency is fixed at 500kHz and also features UVLO, OTP and OCP to protect the circuit.
The AP65251 is available in TSOT26 package providing a high power density leaded solution.
