FN9255.0

Synchronous Buck Pulse-Width

Modulator (PWM) Controller

Features

• Operates from +12V Input

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.

• Excellent Output Voltage Regulation

- 0.597V Internal Reference

- ±1% Over the Commercial Temperature Range

- ±1.5% Over the Industrial Temperature Range

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.

• Simple Single-Loop Control Design

- Voltage-Mode PWM Control

• Fast Transient Response

- High-Bandwidth Error Amplifier

- Full 0% to 100% Duty Ratio

- Leading and Falling Edge Modulation

• Small Converter Size

- Constant Frequency Operation

- Oscillator Programmable from 50kHz to Over 1.5MHz

• 12V High Speed MOSFET Gate Drivers

- 2.0A Source/3A Sink at 12V Low Side Gate Drive

- 1.25A Source/2A Sink at 12V High Side Gate Drive

- Drives Two N-Channel MOSFETs

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

of the upper MOSFET which eliminates

- Reduced ~120ns Blanking Time

• Converter can Source and Sink Current

• Soft-Start Done and an External Reference Pin for

Tracking Applications are Available in the QFN Package

• Pin Compatible with ISL6522

• Supports Start-Up into Prebiased Loads

• Pb-Free Plus Anneal Available (RoHS Compliant)

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
