ISL6540 - Single-Phase Buck PWM Controller

Datasheet Summary

Features

  • provide complete control and protection for a DC/DC converter with minimum external components, resulting in minimum cost and less engineering design efforts. The output voltage of the converter can be precisely regulated with an internal reference voltage of 0.591V, and has a system tolerance of ±0.85% over commercial temperature and line load variations. An external voltage can be used in place of the internal reference for voltage tracking/DDR.

® ISL6540 Data Sheet March 9, 2006 FN9214.0 Single-Phase Buck PWM Controller with Integrated High Speed MOSFET Driver and Pre-Biased Load Capability The ISL6540 is a single-phase voltage-mode PWM controller with input voltage feedforward compensation to maintain a constant loop gain for optimal transient response, especially for applications with a wide input voltage range. Its integrated high speed synchronous rectified MOSFET drivers and other sophisticated features provide complete control and protection for a DC/DC converter with minimum external components, resulting in minimum cost and less engineering design efforts. The output voltage of the converter can be precisely regulated with an internal reference voltage of 0.591V, and has a system tolerance of ±0.
