Advanced Single Synchronous Buck Pulse Width Modulation (PWM) Controller Evaluation Boards

描述

The ISL6420A advanced single synchronous buck pulse width modulation (PWM) controller simplifies the implementation of a complete control and protection scheme for a high-performance DC/DC buck converter. It is designed to drive N-channel MOSFETs in a synchronous rectified buck topology. The control, output adjustment, monitoring, and protection functions are integrated into a single package.

The ISL6420A provides simple, single feedback loop, voltage mode control with fast transient response. The output voltage of the converter can be precisely regulated to as low as 0.6V, with a maximum tolerance of ±1.0% over temperature and line voltage variations.

The ISL6420AEVALxZ evaluation boards have been optimized for a 12V input from a standard power supply but can accept a range from 4.5V to 5.5V or 5.5V to 28V as desired. Standoff terminals have been provided in order to connect the input source and the load.
