FN9214.0

Single-Phas e Buck PWM Controller with

Integrated High Speed MOSFET Driver

and Pre-Bias ed Load Capability

Features

• VIN and Power Rail Operation from +3.3V to +20V

• Fast Transient Response - 0 to 100% Duty Cycle

- 15MHz Bandwidth Error Amplifier with 6V/µs Slew Rate

- Voltage-Mode PWM Leading and Trailing-edge

Modulation Control

- Input Voltage Feedforward Compensation

• 2.9V to 5.6V High Speed 2A/4A MOSFET Gate Drivers

- Tri-state for Power Stage Shutdown

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.

• Internal Linear Regulator (LR) - 5.6V Bias from VIN

• External LR Drive for Optimal Thermal Performance

• Voltage Margining with Independently Adjustable Upper and

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.

Lower Settings for System Stress Testing & Over Clocking

• Reference Voltage I/O for DDR/Tracking Applications

• Precise 0.591V Internal Reference with Buffered Output

- ±0.85%/±1.25% Over Commercial/Industrial Range

• Source and Sink Overcurrent Protections

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.

- Low- and High-Side MOSFET r

Sensing

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.
