The ISL8118EVAL1Z evaluation board highlights the operations of the ISL8118 pulse width modulation (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 top-side and bottom-side 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.
