DATASHEET HIP6004D FN4855 Rev 3.00 Buck and Synchronous-Rectifier (PWM) Controller and Output Voltage Monitor July 13, 2005 The HIP6004D provides complete control and protection for Features a DC-DC converter optimized for high-performance Drives Two N-Channel MOSFETs microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous-rectified buck Operates from +5V or +12V Input topology. The HIP6004D integrates all of the control, output Simple Single-Loop Control Design adjustment, monitoring and protection functions into a single - Voltage-Mode PWM Control package. Fast Transient Response The output voltage of the converter is easily adjusted and - High-Bandwidth Error Amplifier precisely regulated. The HIP6004D includes a fully TTL- - Full 0% to 100% Duty Ratio compatible 5-input digital-to-analog converter (DAC) that adjusts the output voltage from 1.1V to 1.85V in 25mV Excellent Output Voltage Regulation DC DC increments steps. The precision reference and voltage- - 1% Over Line Voltage and Temperature mode regulator hold the selected output voltage to within TTL-Compatible 5-Bit Digital-to-Analog Output 1% over temperature and line voltage variations. Voltage Selection The HIP6004D provides simple, single feedback loop, - 25mV Binary Steps . . . . . . . . . 1.100V to 1.850V DC DC voltage-mode control with fast transient response. It includes Power-Good Output Voltage Monitor a 200kHz free-running triangle-wave oscillator that is Over-Voltage and Over-Current Fault Monitors adjustable from below 50kHz to over 1MHz. The error amplifier features a 15MHz gain-bandwidth product and - Does Not Require Extra Current Sensing Element, Uses MOSFETs r 6V/ s slew rate which enables high converter bandwidth for DS(ON) fast transient performance. The resulting PWM duty ratio Small Converter Size ranges from 0% to 100%. - Constant Frequency Operation The HIP6004D monitors the output voltage with a window - 200kHz Free-Running Oscillator Programmable from 50kHz to over 1MHz comparator that tracks the DAC output and issues a Power Good signal when the output is within 10%. The HIP6004D QFN Package: protects against over-current and overvoltage conditions by - Compliant to JEDEC PUB95 MO-220 inhibiting PWM operation. Additional built-in overvoltage QFN - Quad Flat No Leads - Package Outline protection triggers an external SCR to crowbar the input - Near Chip Scale Package footprint, which improves supply. The HIP6004D monitors the current by using the PCB efficiency and has a thinner profile r of the upper MOSFET which eliminates the need for DS(ON) Pb-Free plus anneal available (RoHS compliant) a current sensing resistor.
