Mouser – Easy-to-use step-down power controllers capable of providing up to 12A (TI LM3151 / LM3152 / LM3153)

Mar 31 2014 - Power [More Power Articles]

Mouser now offers from stock, Texas Instruments’ (TI) Simple Switches controllers – easy-to-use and simplified step-down power controllers capable of providing up to 12A of output current in a typical application.

The TI LM3151 / LM3152 / LM3153 SIMPLE controllers operate with an input voltage range from 6V to 42V, feature a fixed output voltage of 3.3V, and offer switching frequencies of 250kHz, 500kHz, and 750kHz. LM3150 offers adjustable output to 1MHz. The devices employ a constant on-time (COT) architecture with a proprietary emulated ripple mode (ERM) control that allows for the use of low ESR output capacitors, which reduces overall solution size and output voltage ripple. The controllers are designed for use in telecom, networking equipment, security surveillance and similar applications.
