ISL8118EVAL1Z

3.3V to 20V Single-Phase PWM Controller with Integrated 2A/4A MOSFET Driver Evaluation Board

Description

The ISL8118EVAL1Z evaluation board highlights the operations of the ISL8118 PWM controller in a DC/DC application.

The ISL8118 is a single-phase PWM controller for a synchronous buck converter with an integrated MOSFET driver that operates from +3.3V to +20V bias supply voltage. Utilizing voltage-mode operation with input voltage feed-forward compensation, the ISL8118 maintains a constant loop gain, providing optimal transient response for applications with a wide input operating voltage range

The controller features the ability to safely start-up into prebiased output loads and provides protection against overcurrent fault events. Overcurrent protection is implemented using both topside and bottomside MOSFET rDS(ON) sensing, eliminating the need for a current sensing resistor. Dual sensing allows the ISL8118 to detect overcurrent faults at the very low and very high duty cycles that can result from the ISL8118’s wide input range.
