iP1202 Power Block
Description
The iP1202 is a fully optimized solution for medium current synchronous buck applications requiring up to 15A
or 30A. The iP1202 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.

* 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.
