The ISL6431A is a high efficiency, fixed frequency, synchronous buck PWM controller.
It is designed for use in applications that convert 5V to lower distributed
voltages required for DSL modems, cable and DSL routers and broadband gateway core processor, memory and peripheral power supplies.
The ISL6431A makes simple work out of implementing a complete control and protection scheme for a DC-DC stepdown converter.
Designed to drive N-channel
MOSFETs in a synchronous buck topology, the ISL6431A integrates the control, output adjustment, monitoring and protection functi...
