HIP6021A
Advanced PWM and Triple Linear Power
Controller
The HIP6021A provides the power control and protection for
four output voltages in high-performance, graphics intensive
microprocessor and computer applications. The IC
integrates a voltage-mode PWM controller and three linear
controllers, as well as the monitoring and protection
functions into a 28 lead SOIC package.
The synchronous-rectified buck converter includes an Intel-
compatible, TTL 5-input digital-to-analog converter (DAC)
that adjusts the core PWM output voltage from 1.3V
DC
to
2.05V
DC
in 0.05V steps and from 2.1V
DC
to 3.5V
DC
in 0.1V
increments. The precision reference and voltage-mode
control provide
±
1% static regulation. A TTL-compatible
signal applied to the SELECT pin dictates which method of
control is used for the AGP bus power: a low state results in
linear control of the AGP bus to 1.5V, while a high state
transitions the output through a linearly controlled softstart to
3.3V, followed by full enhancement of the external MOSFET
to pass the input voltage. The other two linear regulators
provide fixed output voltages of 1.5V GTL bus power and
1.8V power for the North/South Bridge core and/or cache
memory. These levels are user-adjustable by means of an
external resistor divider and pulling the FIX pin low. All linear
controllers can employ either N-Channel MOSFETs or
bipolar NPNs for the pass transistor.
The HIP6021A monitors all the output voltages. A single
Power Good signal is issued when the core is within
±
10% of
the DAC setting and all other outputs are above their under-
voltage levels. Additional built-in over-voltage protection for
the core output uses the lower MOSFET to prevent output
voltages above 115% of the DAC setting. The PWM
controller’s over-current function monitors the output current
by using the voltage drop across the upper MOSFET’s
r
DS(ON)
.
