Theale, UK — Maxim introduces the MAX8737 , a dual, high-power, linear-regulator controller used with external n-channel MOSFETs to generate two independent low-voltage supplies for notebook computers. The regulator delivers low output voltages from 0.5 V to 2.5 V, and the external MOSFETs allow scalable current design with highly regulated (1 %) loads up to 5 A. The MAX8737 operates from a low input voltage, which also reduces the power dissipation in the external n-channel MOSFETs. An external resistive divider is used to fold back the current limit, thereby reducing the overall power dissipation. An output undervoltage timeout is included for low-cost applications that omit the current-sense resistor. The linear regulator features an adjustable soft-start function, and generates a delayed power-good signal that indicates when the MAX8737 is in regulation. Current and thermal limits prevent damage to the device. The IC is screened for the extended-industrial temperature range. and is available in a small, 16-pin, 4 x 4mm TQFN package. Pricing starts at $1.29 (1000-up, FOB USA). A preassembled MAX8737EVKIT with recommended external components is available to reduce design time.
