ISL6527
Single Synchronous Buck Pulse-Width
Modulation (PWM) Controller
The ISL6527 makes simple work out of implementing a
complete control and protection scheme for a DC-DC
stepdown converter. Designed to drive N-Channel
MOSFETs in a synchronous buck topology, the ISL6527
integrates the control, output adjustment, monitoring and
protection functions into a single package.
The ISL6527 provides simple, single feedback loop, voltage-
mode control with fast transient response. The output voltage
can be regulated to as low as the provided external reference.
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/
μ
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.
