DIODES Incorporated DC DC Switching Controllers AP3102MTR-G1

The AP3102MTR-G1 is a green-mode PWM controller designed for DC-DC switching applications, featuring low start-up current of 5OºA typical. It operates with an externally programmable switching frequency, enhanced by frequency dithering to improve electromagnetic interference (EMI) performance. The controller enters a green mode at low or zero load to minimize switching losses, maintaining a PWM frequency of approximately 20kHz to avoid audible noise. This controller includes several protective features such as cycle-by-cycle current limit, over voltage protection, over temperature protection, and brownout protection. It supports various configurations with options for latch shutdown and auto-recoverable protection. The device is packaged in an SO-8 format and is compliant with RoHS and green standards, making it suitable for environmentally conscious designs. Typical applications include switching AC-DC adapters, LCD monitor and TV power supplies, and open frame switching power supplies. The AP3102MTR-G1 is a versatile choice for engineers looking for a reliable and efficient DC-DC controller.
