DIODES Incorporated AC DC Converters, Offline Switches AP39811BS7-13

The AP39811BS7-13 is a high-performance power switcher designed for shaver charger applications. It integrates a primary side regulation controller and a built-in 650V N-channel power MOSFET, eliminating the need for an opto-coupler and secondary control circuitry. The device operates in Pulse Frequency Modulation (PFM) and peak current Amplitude Modulation (AM) modes, allowing for fine-tuning of the frequency curve across the power range, which enhances efficiency and minimizes audible noise. This product features a slew rate adjustment for the slant IV curve through a resistor connected between the FB and CPR pins. It includes multiple built-in protections such as over voltage protection, bulk capacitor open protection, transformer saturation protection, and over temperature protection, ensuring reliable operation without additional circuitry. The AP39811BS7-13 is packaged in an SO-7 format and is compliant with RoHS standards, making it suitable for environmentally conscious designs.
