ME8302

Descriptionú║
The ME8302 is a high performance AC/DC power supply controller for battery charger and adapter applications. The device uses pulse frequency modulation (PFM) method to build discontinuous conduction mode(DCM) flyback power supplies.
The ME8302 provides accurate constant voltage, constant current(CV/CC) regulation without requiring an Opto-coupler and secondary control circuitry. It also eliminates the need of loop compensation circuitry while maintaining stability. The ME8302 achieves excellent regulation and high average efficiency, yet meets the requirement for no-load consumption less than 30mW.
The ME8302 has the built-in programmable cable voltage drop compensation function, which make it flexible to accommodate various cables with different gauges and lengths.
