General Description
The MAX8737 dual high-power linear regulator controllers use external n-channel MOSFETs to generate two independent low-voltage supplies for notebook computers. The MAX8737 delivers low output voltages from 0.5V to 2.5V (±5mV no-load accuracy). The external components allow scalable current design with loads up to 5A with excellent load regulation (1%). The regulator operates from a low input voltage, which also reduces the power dissipation in the external n-channel MOSFET. The controller powers the external MOSFET gate driver from the standard 5V system supply.
