ISL6439, ISL6439A

Data Sheet

September 15, 2015

FN9057.6

Single Sync Buck PWM Controller for

Broadband Gateway Applications

The ISL6439 makes easy work out of implementing a

complete control and protection scheme for a DC/DC

step-down converter. Designed to drive N-Channel

MOSFETs in a synchronous buck topology, the ISL6439

integrates the control, output adjustment, monitoring and

protection functions into a single package.

The ISL6439 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, with a

maximum tolerance of ±1.5% over temperature and line

voltage variations. A fixed frequency oscillator reduces

design complexity, while balancing typical application cost

and efficiency.

The error amplifier features a 15MHz gain-bandwidth

product and 6V/s slew rate which enables high converter

bandwidth for fast transient performance. The resulting

PWM duty cycles range from 0% to 100%.

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.
