ISL6540A  
®
Data Sheet  
October 7, 2008  
FN6288.5  
Single-Phase Buck PWM Controller with  
Integrated High Speed MOSFET Driver  
and Pre-Biased 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  
The ISL6540A is an improved version of the ISL6540  
single-phase voltage-mode PWM controller with input voltage  
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  
• Voltage Margining with Independently Adjustable Upper and  
Lower Settings for System Stress Testing and Over Clocking  
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.  
• Reference Voltage I/O for DDR/Tracking Applications  
• Improved 0.591V Internal Reference with Buffered Output  
- ±0.68%/±1.0% Over Commercial/Industrial Range  
• Source and Sink Overcurrent Protections  
- Low-and High-Side MOSFET r  
Sensing  
DS(ON)  
• Overvoltage and Undervoltage Protections  
• Small Converter Size - QFN package  
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.  
• 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.
