ISL6406
Single Synchronous Buck Pulse-Width
Modulation (PWM) Controller
The ISL6406 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.
Designed to drive N-Channel MOSFETs in synchronous
buck topology, the ISL6406 integrates the control, output
adjustment and protection functions into a single package.
The ISL6406 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.
