ISL6406, ISL6426
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.
The error amplifier features a 15MHz gain-bandwidth
product and 6V/
μ
s slew rate which enables high converter
bandwidth for fast transient performance.
Protection from overcurrent conditions is provided by
monitoring the r
DS(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 capacitors. The device also provides external
frequency synchronization making it an ideal choice for
DC-DC converter applications.
