ISL6545A, ISL6545, 5V or 12V Single Synchronous Buck Pulse-Width Modulation Controller
® Data Sheet ISL6545, ISL6545A April 29, 2010 FN6305.5 5V or 12V Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6545 makes simple work out of implementing a complete control and protection scheme for a DC/DC stepdown converter driving N-Channel MOSFETs in a synchronous buck topology.
Since it can work with either 5V or 12V supplies, this one IC can be used in a wide variety of applications within a system.
The ISL6545 integrates the control, gate drivers, output adjus
ISL6545A Features
* a 20MHz gain-bandwidth product and 9V/µs slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty cycles range from 0% to 100%. Protection from overcurrent conditions is provided by monitoring the rDS(ON) of the lower MOSFET to inhibit PWM operation app
