The ISL6740EVAL3Z serves as a reference design for a 48V to ±12V, 3.3V and 1.5V isolated power supply. It utilizes an ISL6740 double-ended voltage mode controller in half bridge topology to provide an isolated 48V to ±12V conversion. An ISL6402 dual PWM controller in synchronous buck topology provides the 3.3V and 1.5V outputs from the +12V rail. The reference design also provides pads to implement an optional LDO using the ISL6402 as a controller.
The ISL6740 adjustable frequency, low power, pulse width modulating (PWM) voltage mode controllers are designed for a wide range of power conversion applications using half-bridge, full bridge, and push-pull configurations. These controllers provide an extremely flexible oscillator that allows precise control of frequency, duty cycle, and deadtime.
