MAX8737
Description
The MAX8737 dual high-power linear regulator controllers use external n-channel MOSFETs to generate two independent low-voltage supplies for notebook puters. The MAX8737 delivers low output voltages from 0.5V to 2.5V (±5m V no-load accuracy). The external ponents 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.
The MAX8737 includes current and thermal limits to prevent damage to the linear regulator. The MAX8737 uses an external resistive divider to fold back the current limit, reducing the overall power dissipation. The MAX8737 uses an external resistive-divider in series with the current-sense input (CS_), providing foldback current-limit protection, and effectively reducing the short-circuit power dissipation.
