LM5019 - Buck Regulator

General Description

The LM5019 is a 100-V, 100-mA synchronous stepdown regulator with integrated high-side and low-side MOSFETs.

The constant-on-time (COT) control scheme employed in the LM5019 requires no loop compensation, provides excellent transient response, and enables very low step-down ratios.

Key Features

  • 1 Wide 7.5-V to 100-V Input Range.
  • Integrated 100-mA High-Side and Low-Side Switches.
  • No Schottky Required.
  • Constant On-Time Control.
  • No Loop Compensation Required.
  • Ultra-Fast Transient Response.
  • Nearly Constant Operating Frequency.
  • Intelligent Peak Current Limit.
  • Adjustable Output Voltage From 1.225 V.
  • Precision 2% Feedback Reference.
  • Frequency Adjustable to 1 MHz.
  • Adjustable Undervoltage.
