LM25018 Datasheet 325-ma Constant On-time Synchronous Regulator

Manufacturer: Texas Instruments

Overview: LM25018 SNVS953G – DECEMBER 2012 – REVISED MAY 2021 LM25018 48-V, 325-mA Constant On-Time Synchronous Buck/Fly-Buck™ Regulator.

General Description

The LM25018 device is a 48-V, 325-mA synchronous step-down regulator with integrated high-side and low-side MOSFETs.

The constant on-time (COT) control scheme employed in the LM25018 device requires no loop compensation, provides excellent transient response, and enables very high step-down ratios.

The on-time varies inversely with the input voltage resulting in nearly constant frequency over the input voltage range.

Key Features

  • Wide 7.5-V to 48-V input range.
  • Integrated 325-mA, high-side and low-side switches.
  • No schottky required.
