LM5017 - 600-mA Constant On-Time Synchronous Buck Regulator

General Description

The LM5017 is a 100-V, 600-mA synchronous stepdown regulator with integrated high side and low side MOSFETs.

The constant on-time (COT) control scheme employed in the LM5017 requires no loop compensation, provides excellent transient response, and enables very high step-down ratios.

Key Features

  • Wide 7.5-V to 100-V input range.
  • Integrated 100-V 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 l.
