ISL6406MR

Data Sheet ISL6406MR, ISL6406MV November 11, 2011 FN6613.1 Enhanced Product (EP) Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6406MREP and ISL6406MVEP are adjustable frequency, synchronous buck switching regulators optimized for generating lower voltages for distributed DC/DC architectures. Both devices feature an adjustable output voltage. Designed to drive N-Channel MOSFETs in a synchronous buck topology, the ISL6406MREP and ISL6406MVEP integrate the control, output adjustment and protection functions into a single package. The ISL6406MREP and ISL6406MVEP provide simple, single feedback loop, voltage-mode control with fast transient response. The output voltage can be precisely regulated to as low as 0.8V. The error amplifier features a 15MHz gain-bandwidth product and 6V/μs slew rate which enables high converter bandwidth for fast transient performance. Protection from overcurrent conditions is provided by monitoring the rDS(ON) of the upper MOSFET to ...
