ISL6540

July 23, 2008

FN9214.1

Single-Phase Buck PWM Controller with

Integrated High Speed MOSFET Driver

and Pre-Biased Load Capability

The ISL6540 is a single-phase voltage-mode PWM controller

with input voltage feedforward compensation to maintain a

constant loop gain for optimal transient response, especially for

applications with a wide input voltage range. Its integrated high

speed synchronous rectified MOSFET drivers and other

sophisticated features provide complete control and protection

for a DC/DC converter with minimum external components,

resulting in minimum cost and less engineering design efforts.

The output voltage of the converter can be precisely regulated

with an internal reference voltage of 0.591V, and has a system

tolerance of ±0.85% over commercial temperature and line load

variations. An external voltage can be used in place of the

internal reference for voltage tracking/DDR applications.

The ISL6540 has an internal linear regulator or external linear

regulator drive options for applications with only a single supply

rail. The internal oscillator is adjustable from 250kHz to 2MHz.

The integrated voltage margining, programmable pre-biased

soft-start, differential remote sensing amplifier, and

programmable input voltage POR features enhance the

ISL6540 value.

NOTE: These Intersil Pb-free plastic packaged products employ

special Pb-free material sets, molding compounds/die attach

materials, and 100% matte tin plate plus anneal (e3 termination

finish, which is 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.
