Buck Pulse-width Modulator (pwm) Controller And Output Voltage Monitor

The HIP6011 provides complete control and protection for a DC-DC Converter optimized for high-performance micropro- cessor applications. It is designed to drive an N-Channel MOSFET in a standard buck topology. The HIP6011 inte- grates all of the control, output adjustment, monitoring and protection functions into a single package. The output voltage of the converter CAN be precisely regu- lated to as low as 1.27V, with a maximum tolerance of 1.5% over temperature and line voltage variations. The HIP6011 provides simple, single feedback loop, voltage- mode control with fast transient response. It includes a 200kHz free-running triangle-wave Oscillator that is adjust- able from below 50kHz to over 1MHz. The error amplier features a 15MHz gain-bandwidth product and 6V/s slew rate which enables high converter bandwidth for fast tran- sient performance. The resulting PWM duty ratio ranges from 0% to 100%. The HIP6011 protects against over-current conditions by inhib- iting PWM operation. The HIP6011 monitors the current by using the rDS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor. Built-in over-voltage protec- tion triggers an external SCR to crowbar the input supply. By Intersil Corporation
