DATASHEET
ISL6535
Synchronous Buck Pulse-Width Modulator (PWM) Controller
The
ISL6535
is a high performance synchronous controller for
demanding DC/DC converter applications. It provides
overcurrent fault protection and is designed to safely start-up
into prebiased output loads.
The output voltage of the converter can be precisely regulated
to as low as 0.597V, with a maximum tolerance of ±1% over
the commercial temperature range, and ±1.5% over the
industrial temperature range.
The ISL6535 provides simple, single feedback loop, voltage
mode control with fast transient response. It includes a
triangle wave oscillator that is adjustable from below 50kHz to
over 1.5MHz. Full (0% to 100%) PWM duty cycle support is
provided.
The error amplifier features a 15MHz gain bandwidth product
and 6V/µs slew rate, which enables high converter bandwidth
for fast transient performance.
The ISL6535's overcurrent protection monitors the current by
using the
r
DS(ON)
of the upper MOSFET, which eliminates the
need for a current sensing resistor.
