LM5148-Q1 - Texas Instruments

LM5148-Q1 Buck DC/DC Controller

The LM5148-Q1 is a 80-V, ultra-low IQ synchronous buck DC/DC controller for high-current, single-output applications. The controller uses a peak current-mode control architecture for easy loop compensation, fast transient response, and excellent load and line regulation. The LM5148-Q1 can be set up in idualphase mode (paralleled output) with accurate curren.
