DATASHEET  
ISL6525  
FN4998  
Rev 3.00  
Dec 27, 2004  
Buck and Synchronous-Rectifier Pulse-Width Modulator (PWM) Controller  
The ISL6525 provides complete control and protection for a  
DC-DC converter optimized for high-performance  
Features  
• Drives Two N-Channel MOSFETs  
microprocessor applications. It is designed to drive two  
N Channel MOSFETs in a synchronous-rectified buck  
topology. The ISL6525 integrates all of the control, output  
adjustment, monitoring and protection functions into a single  
package. A programmable delay time for the PGOOD signal  
makes it especially suitable for the VTT regulation in  
VRM8.5 applications.  
• Operates From +5V or +12V Input  
• Simple Single-Loop Control Design  
- Voltage-Mode PWM Control  
• Fast Transient Response  
- High-Bandwidth Error Amplifier  
- Full 0% to 100% Duty Ratio  
The output voltage of the converter can be precisely  
regulated to as low as 1.20V, with a maximum tolerance of  
1% over temperature and line voltage variations.  
• Excellent Output Voltage Regulation  
- 1.20V Internal Reference  
- 1% Over Line Voltage and Temperature  
The ISL6525 provides simple, single feedback loop, voltage-  
mode control with fast transient response. It includes a  
200kHz free-running triangle-wave oscillator that is  
adjustable from below 50kHz to over 1MHz. The error  
amplifier features a 15MHz gain-bandwidth product and  
6V/s slew rate which enables high converter bandwidth for  
fast transient performance. The resulting PWM duty ratio  
ranges from 0% to 100%.  
• Programmable delay for PGOOD signal  
• Over-Current Fault Monitor  
- Does Not Require Extra Current Sensing Element  
- Uses MOSFETs r  
DS(ON)  
• Small Converter Size  
- Constant Frequency Operation  
- 200kHz Free-Running Oscillator Programmable from  
50kHz to Over 1MHz  
The ISL6525 protects against over-current conditions by  
inhibiting PWM operation. The ISL6525 monitors the current  
by using the r  
of the upper MOSFET which eliminates  
• 14 Pin, SOIC Package  
DS(ON)  
the need for a current sensing resistor.  
• Pb-Free Available (RoHS Compliant)

NOTE: Intersil Pb-free 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.
