Buck and Synchronous-Rectifier  
Features  
Pulse-Width Modulator (PWM) Controller  
• Drives Two N-Channel MOSFETs  
• Operates From +5V or +12V Input  
The HIP6006 provides complete control and protection for a  
DC-DC converter optimized for high-performance  
microprocessor applications. It is designed to drive two  
N Channel MOSFETs in a synchronous-rectified buck  
topology. The HIP6006 integrates all of the control, output  
adjustment, monitoring and protection functions into a single  
package.  
• 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 1.27V, with a maximum tolerance of  
±1% over temperature and line voltage variations.  
• Excellent Output Voltage Regulation  
- 1.27V Internal Reference  
- ±1% Over Line Voltage and Temperature  
The HIP6006 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 performance. The resulting PWM duty ratio  
ranges from 0% to 100%.  
• 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 HIP6006 protects against over-current conditions by  
inhibiting PWM operation. The HIP6006 monitors the current
