Buck and Synchronous-Rectifier
Pulse-Width Modulator (PWM) Controller
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, 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%.
The HIP6012 protects against overcurrent conditions by
inhibiting PWM operation. The HIP6012 monitors the current
by using the r
the need for a current sensing resistor.
