Diodes' AP65111 and AP65211 are current-mode synchronous buck converters providing high efficiency, excellent transient response, and high DC output accuracy. Both incorporate control algorithms that improve efficiency at light loads. They operate at a fixed 500 kHz switching frequency which provides a good balance between low power dissipation and small solution size form factor. Also featuring UVLO, OTP, and OCP to protect the circuit. They are available in TSOT26 packages providing a high-power density leaded solution.
