Description
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 amplifier
features a 15MHz gain-bandwidth product and 6V/
μ
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 r
DS(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.
