Single-Phase Buck PWM Controller with
Integrated High Speed MOSFET Driver
and Pre-Biased Load Capability
The ISL6540A is an improved version of the ISL6540
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 an
improved system tolerance of ±0.68% 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 ISL6540A 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
ISL6540A value.

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.
