Introduction

AI Translation

The LM5017 is a 100V, 600mA synchronous buck regulator with integrated high-side and low-side MOSFETs. The constant on-time (COT) control scheme eliminates the need for loop compensation, delivers excellent transient response, and enables very high step-down ratios. The on-time varies inversely with input voltage, maintaining a nearly constant frequency across the entire input voltage range. A high-voltage startup regulator provides bias power for internal IC operation and the integrated gate drivers.

A peak current limit circuit protects against overload conditions. The UVLO circuit allows independent programming of the input undervoltage threshold and hysteresis. Additional protection features include thermal shutdown and bias supply undervoltage lockout (VCC UVLO).
