ISL6540A

FN6288

Rev 5.00

Oct 7, 2008

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

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

feed-forward 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.

- Input Voltage Feedforward Compensation

• 2.9V to 5.5V High Speed 2A/4A MOSFET Gate Drivers

- Tri-state for Power Stage Shutdown

• Internal Linear Regulator (LR) - 5.5V Bias from VIN

• External LR Drive for Optimal Thermal Performance

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.

• Voltage Margining with Independently Adjustable Upper and

Lower Settings for System Stress Testing and Over Clocking

• Reference Voltage I/O for DDR/Tracking Applications

• Improved 0.591V Internal Reference with Buffered Output

- ±0.68%/±1.0% Over Commercial/Industrial Range

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.

• Source and Sink Overcurrent Protections

- Low-and High-Side MOSFET r

Sensing

DS(ON)

• Overvoltage and Undervoltage Protections

• Small Converter Size - QFN package

• Oscillator Programmable from 250kHz to 2MHz

• Differential Remote Voltage Sensing with Unity Gain

• Programmable Soft-Start with Pre-Biased Load Capability

• Power-Good Indication with Programmable Delay

• EN Input with Voltage Monitoring Capability

• Pb-Free (RoHS Compliant)

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.
