Buck and Synchronous Rectifier Pulse-Width Modulator (PWM) Controller  
The ISL6522B provides complete control and protection for a  
DC-DC converter optimized for high-performance  
Features  
• Drives two N-Channel MOSFETs  
• Operates from +5V or +12V input  
microprocessor applications. It is designed to drive two  
N-Channel MOSFETs in a synchronous rectified buck topology.  
The ISL6522B integrates all of the control, output adjustment,  
monitoring and protection functions into a single package.  
• Simple single-loop control design  
- Voltage-mode PWM control  
The output voltage of the converter can be precisely  
regulated to as low as 0.8V, with a maximum tolerance of  
1% over temperature and line voltage variations.  
• Fast transient response  
- High-bandwidth error amplifier  
- Full 0–100% duty ratio  
The ISL6522B 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/µs slew rate which  
enables high converter bandwidth for fast transient perform-  
ance. The resulting PWM duty ratio ranges from 0-100%.  
• Excellent output voltage regulation  
- 0.8V internal reference  
- 1% over line voltage and temperature  
• Overcurrent fault monitor  
- Does not require extra current sensing element  
- Uses MOSFETs r  
DS(ON)  
The ISL6522B protects against overcurrent conditions by  
inhibiting PWM operation. The ISL6522B monitors the  
• Converter can source and sink current  
• Pre-Biased Load Start Up  
current by using the r  
of the upper MOSFET which  
DS(ON)  
• Small converter size  
eliminates the need for a current sensing resistor.  
- Constant frequency operation  
- 200kHz free-running oscillator programmable from  
50kHz to over 1MHz
