ISL6406 Single Synchronous Buck Pulse-Width Modulation (PWM) Controller

CPVOUT - This pin represents the output of the charge pump. The voltage at this pin is the bias voltage for the IC. Connect a decoupling capacitor from this pin to ground. The value of the decoupling capacitor should be at least 10x the value of the charge pump capacitor. This pin may be tied to th.

® ISL6406, ISL6426 Data Sheet October 2003 FN9073.4 Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6406, ISL6426 is an adjustable frequency, synchronous buck switching regulator optimized for generating lower voltages for the distributed DC-DC architectures. The ISL6406 offers an adjustable output voltage, while the ISL6426 provides a fixed 1.8V output. Designed to drive N-Channel MOSFETs in synchronous buck topology, the ISL6406, ISL6426 integrates the control, output .

ISL6406 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 inhibit PWM operation appropriately. This approach simplifies the implementati
