iP2003 Power Block
Description
The iP2003 is a fully optimized solution for high current synchronous buck multiphase applications.
Board space and design time are greatly reduced because most of the components required for each
phase of a typical discrete-based multiphase circuit are integrated into a single 11mm x 11mm x 2.2mm
power block. The only additional components required for a complete multiphase converter are a PWM IC, the
external inductors, and the input and output capacitors.
iPOWIR technology offers designers an innovative board space saving solution for applications
requiring high power densities. iPOWIR technology eases design for applications where component integration
offers benefits in performance and functionality. iPOWIR technology solutions are also optimized internally for
layout, heat transfer and component selection.

DD
Supply voltage for the internal circuitry.
When set to logic level high, internal circuitry
of the device is enabled. When set to logic
level low, the PRDY pin is forced low, the
Control and Sychronous switches are turned
off, and the supply current is less than 10碌A(chǔ).
TTL-level input signal to MOSFET drivers.
Power Ready - This pin indicates the status of
ENABLE or V
DD
. This output will be driven
low when ENABLE is logic low or when V
DD
is less than 4.4V (typ.). When ENABLE is
logic high and V
DD
is greater than 4.4V (typ.),
this output is driven high. This output has a
10mA source and 1mA sink capability.
Power Ground - connection to the ground of
bulk and filter capacitors.
Switching Node - connection to the output
inductor.
