The ISL62383HIEVAL1Z evaluation board demonstrates the performance of the ISL62383 triple-output controller. The ISL62383 controller includes two pulse width modulation (PWM) controllers featured with Renesas' patented R3 technology, adjustable from 0.6V to 5.5V, and one linear regulator LDO5, which generates a fixed 5V output and can deliver up to 100mA.
The evaluation board includes two independent Enable switches, two LED Power-Good (PGOOD) indicators and various test points. Included with each switching channel is an on-board dynamic load generator for evaluating the transient-load response. There are two different evaluation boards which provide flexible evaluation options.
