HIP6006 Data Sheet April 1, 2005 FN4306.3 Buck and Synchronous-Rectifier Features Pulse-Width Modulator (PWM) Controller Drives Two N-Channel MOSFETs The HIP6006 provides complete control and protection for a Operates From +5V or +12V Input DC-DC converter optimized for high-performance Simple Single-Loop Control Design microprocessor applications. It is designed to drive two N Channel MOSFETs in a synchronous-rectified buck - Voltage-Mode PWM Control topology. The HIP6006 integrates all of the control, output Fast Transient Response adjustment, monitoring and protection functions into a single - High-Bandwidth Error Amplifier package. - Full 0% to 100% Duty Ratio The output voltage of the converter can be precisely Excellent Output Voltage Regulation regulated to as low as 1.27V, with a maximum tolerance of - 1.27V Internal Reference 1% over temperature and line voltage variations. - 1% Over Line Voltage and Temperature The HIP6006 provides simple, single feedback loop, voltage- Over-Current Fault Monitor mode control with fast transient response. It includes a - Does Not Require Extra Current Sensing Element 200kHz free-running triangle-wave oscillator that is - Uses MOSFETs r DS(ON) adjustable from below 50kHz to over 1MHz. The error amplifier features a 15MHz gain-bandwidth product and Small Converter Size 6V/ s slew rate which enables high converter bandwidth for - Constant Frequency Operation fast transient performance. The resulting PWM duty ratio - 200kHz Free-Running Oscillator Programmable from ranges from 0% to 100%. 50kHz to Over 1MHz The HIP6006 protects against over-current conditions by 14 Pin, SOIC and TSSOP Package inhibiting PWM operation. The HIP6006 monitors the current Pb-Free Available (RoHS Compliant) by using the r of the upper MOSFET which eliminates DS(ON) the need for a current sensing resistor.
