The ISL6745EVAL1Z evaluation board utilizes Intersil’s double-ended voltage-mode PWM controller ISL6745A for half-bridge converters with secondary side synchronous rectification. The voltage mode PWM controller ISL6745 is a 10 Ld MSOP device.
The input of the evaluation board ranges from 36V to 75V, and the output voltage is regulated to 12V with a maximum load current of 10A. Planar transformers and inductors are used. The triple-output linear regulator ISL6720A is used to provide bias for the primary side controller and drivers.
