HIP6013
FN4325.1
Buck Pulse-Width Modulator (PWM)
Controller
The HIP6013 provides complete control and protection for a
DC-DC converter optimized for high-performance
microprocessor applications. It is designed to drive an
N-Channel MOSFET in a standard buck topology. The
HIP6013 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 HIP6013 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 HIP6013 protects against over-current conditions by
inhibiting PWM operation. The HIP6013 monitors the current
by using the r_DS(ON) of the upper MOSFET which eliminates
the need for a current sensing resistor.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
