DIODES Incorporated Voltage Regulators - DC DC Switching Regulators AP3417AKTR-G1

The AP3417AKTR-G1 is a synchronous buck DC-DC converter designed for high efficiency and compact applications. It operates at a fixed frequency of 1.4MHz and can deliver an output current of up to 1A. The input voltage range is from 2.5V to 5.5V, with an adjustable output voltage capability from 0.6V to VIN. The device features built-in protections including over current, short circuit, thermal shutdown, and under-voltage lockout (UVLO), ensuring reliable operation in various conditions. The AP3417AKTR-G1 is packaged in a SOT-23-5 format, making it suitable for space-constrained designs. It is particularly well-suited for applications in portable devices, smartphones, and set-top boxes. The integration of low on-resistance power MOSFETs contributes to its high efficiency, which can reach up to 95%. This product simplifies the design of switch-mode power supplies by allowing the use of standard inductors optimized for its operation.
