File Number 4306.1
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
