High-efficiency Notebook Computer Power Supply Controller - Analog Devices

The ADP3020 is a highly efcient dual synchronous buck switch- ing Regulator controller optimized for converting the battery or adapter input into the system supply voltages required in note- book computers. The ADP3020 uses a dual-mode PWM/Power Saving Mode architecture to maintain efciency over a wide load range. The Oscillator frequency CAN be programmed for 200 kHz, 300 kHz, or 400 kHz operation, or it CAN be synchro- nized to an external Clock signal of up to 600 kHz. The ADP3020 provides accurate and reliable short circuit pro- tection using an internal Current Sense circuit, which reduces cost and increases overall efciency. Other protection features include programmable soft-start, UVLO, and integrated output undervoltage/overvoltage protection. The ADP3020 contains a linear Regulator controller that is designed to drive an external P-Channel MOSFET or PNP Transistor The linear Regulator output is adjustable, and CAN be used to generate the auxiliary voltages required in many laptop designs.
