LMR12007 - Texas Instruments

LMR12007 Step-Down DC-DC Regulator

The LMR12007 regulator is a monolithic, high frequency, PWM step-down DC/DC converter in a 6pin Thin SOT package. It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components and online design support through WEBENCH®, the L.
