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 startup
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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate termination finish,
which are RoHS compliant and compatible with both SnPb and Pb-free soldering
operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
