July 23, 2008  
FN9214.1  
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 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.  
- Input Voltage Feedforward Compensation  
• 2.9V to 5.6V High Speed 2A/4A MOSFET Gate Drivers  
- Tri-state for Power Stage Shutdown  
Internal Linear Regulator (LR) - 5.6V Bias from VIN  
External LR Drive for Optimal Thermal Performance  
• Voltage Margining with Independently Adjustable Upper and  
Lower Settings for System Stress Testing & Over Clocking  
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.  
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

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 Plus Anneal Available (RoHS Compliant)

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.
