* Although, all of the difficult PCB layout and bypassing issues have been addressed with the internal design of the iPOWIR block, proper layout techniques

should be applied for the design of the power supply board. The iPOWIR block will function normally, but not optimally without any additional input decoupling

capacitors. Input decoupling capacitors should be added at Vin pin for stable and reliable long term operation. See layout guidelines in datasheet for more

detailed information.

iP1202PbF Power Block

Features

Dual Output Full Function 2 Phase

Synchronous Buck Power Block

Integrated Power Semiconductors,

PWM Control & Passives

The iP1202PbF is a fully optimized solution for medium current synchronous buck applications requiring up to

15A or 30A. The iP1202PbF is optimized for 2 phase single output applications up to 30A or dual output, each

up to 15A with interleaved input. It includes full function PWM control, with optimized power semiconductor chip-

sets 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.
