FN9255.1
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.
