Transient Voltage Regulator
DeCAPitator™
The Intersil DeCAPitator helps to stabilize a power system
voltage during severe transients. It accomplishes this by
supplying current when the voltage is more than 1% low or
sinking current when the voltage is higher than 1.5% from
the average load voltage. The fast transient response of the
DeCAPitator can make up for the slow response time of
many switching DC-DC converters.
Although the HIP6200 serves as a simple replacement for
large output capacitors for any dynamic load, it is especially
useful in stabilizing the CPU core voltage in portable
computer applications, where size and efficiency are major
concerns. The DeCAPitator enables power supply designs
for more powerful microprocessors without increasing
converter size or decreasing converter efficiency.
The DeCAPitator acts independently of the PWM control
circuitry. This simplifies converter layout because the
DeCAPitator and the load may be located separately from
the DC-DC converter. The DeCAPitator should be located
near the load for optimum performance.

Functional Pin Description
PVCC (Pin 1)
PVCC is the power source for the npn transistor output
device. PVCC is connected internally to VCC through a
resistor. Bulk capacitance should be placed between this pin
and PGND to minimize voltage deviations.
PGND (Pin 2)
PGND is power ground for the N-Channel MOSFET output
device. Tie this pin to the ground plane of the circuit board.
GND (Pin 3)
GND is signal ground for the IC. Tie this pin to the ground
plane of the circuit board.
VCC (Pin 4)
VCC provides bias power to the chip. It should be tied to
system 5V. Provide local decoupling to this pin.
CAP (Pin 5)
Connect a capacitor to GND to set the internal amplifiers’
on-time response to a rapid voltage change at the SNS pin.
SNS (Pin 6)
SNS is the remote sense of the output voltage to be
regulated. If the output voltage increases rapidly by greater
than 1.5%, the lower amplifier responds by turning on the N-
Channel MOSFET to sink current through the OUT pin to
PGND. If the output voltage decreases rapidly by greater
than 1%, the upper amplifier responds by turning on the npn
transistor to source current from PVCC to OUT.
OUT (Pin 7)
This pin is the output pin of the IC. Tie this pin directly to the
voltage to be regulated.
EN/OT or EN (Pin 8)
This pin is the only differentiation between the HIP6200 and
the HIP6201.
On the HIP6200, this pin is multiplexed. It is chip enable and
also an overtemperature indicator. When this pin is low, the
chip is disabled. If an overtemperature occurs, this pin will be
pulled low internally. Tie EN/OT to a pull-up resistor and
drive with an open collector signal.
On the HIP6201, this pin is chip enable only. Pulling it low
disables the IC. EN should be driven with a logic signal.
