SP6137 - Wide Input / 900KHz Synchronous PWM Controller

Description

The SP6137 is a synchronous step-down switching regulator controller optimized for high efficiency.

The part is designed to be especially attractive for dual supply, 12V step down with 5V used to power the controller.

This lower VCC voltage minimizes power dissipation in the part.

Features

  • 2.5V to 20V Step Down Achieved Using Dual Input Small 10-Pin MSOP Package 2A to 15A Ouput Capability Highly Integrated Design, Minimal Components UVLO Detects Both VCC and VIN Short Circuit Protection with Auto-Restart On-Board 1.5Ω sink (2Ω source) NFET Drivers Programmable Soft Start Fast Transient Response High Efficiency: Greater than 94% Possible A Synchronous Start-Up into a Pre-Charged Output VCC 1 GL 2 GND 3 VFB 4 COMP 5.
