iP1203PbF Power Block
Description
The iP1203PbF is a fully optimized solution for medium current synchronous buck applications requiring up to
15A. It includes full function PWM control, with optimized power semiconductor chipsets and associated
passives, achieving high power density. Very few external components are required to create a complete
synchronous buck power supply.
iPOWIR™ technology offers designers an innovative 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.

RT
Switching frequency setting pin. For RT selection, refer to Fig.9 of the
datasheet
PGOOD
Power Good pin. Open collector, requires external pulll-up. If function not
needed, pin can be left floating
VREF
Non inverting input of the error amplifier (reference Voltage pin). Connect a
100pF cap from this pin to PGND.
SYNC
External Clock synchronization pin. Set free running frequency to 80% of
the SYNC frequency. When not in use, leave pin floating
