HIP6012
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 HIP60012 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/
μ
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 over-current conditions by
inhibiting PWM operation. The HIP6012 monitors the current
by using the r
DS(ON)
of the upper MOSFET which eliminates
the need for a current sensing resistor.
