ISL6406 Datasheet Single Synchronous Buck Pulse-width Modulation (pwm) Controller

Manufacturer: Intersil (now Renesas)

Overview: ® 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 adjustment and protection functions into a single package. The ISL6406, ISL6426 provides simple, single feedback loop, voltage-mode control with fast transient response. The output voltage can be precisely regulated to as low as 0.8V.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key 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 implementation and improves efficiency by eliminating the need for a current sense resistor. The wide programmable switching frequency range of 100kHz to 700kHz allows the use of small surface mount inductors and.
