DATASHEET HIP6012 Buck and Synchronous-Rectifier Pulse-Width Modulator (PWM) Controller FN4324 Rev.
2.
00 December 27, 2004 The HIP6012 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 HIP6012 integrates all of the control, output adjustment, monitoring and protection functions into a single package.
The output voltage of the converter can be precisely regulated to as low as 1.
27V, with a maximum tolerance of 1.
5% over temperature and line voltage variations.
The HIP6012 provides simple, single feedback loop, voltagemode 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/s slew rate which enables high converter bandwidth for fast transient performance.
The resulting PWM duty ratio ranges from 0% to 100%.
The HIP6012 protects against overcurrent conditions by inhibiting PWM operation.
The HIP6012 monitors the current by using the rDS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor.
