Product Summary

The ADP3020A is a high-efficiency notebook computer power supply controller. It is optimized for converting the battery or adapter input into the system supply voltages required in notebook computers. The ADP3020A uses a dual-mode PWM/Power Saving Mode architecture to maintain efficiency over a wide load range. The oscillator frequency can be programmed for 200 kHz, 300 kHz, or 400 kHz operation, or it can be synchronized to an external clock signal of up to 600 kHz.
