Description
The iP1201 PbF is a fully optimized solution for medium current synchronous buck applications requiring upto15A
or 30A. The iP1201PbF 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 powersemiconductorchip-sets and
associated passives, achieving high power density. Very few external components are required to create a complete
synchronous buck power supply.
iPOWlR technology offers designers an innovative space-saving solution for applications requiring high power
densities. iPOWlR technology eases design for applications where component integration offers benefits in
performance and functionality. iPOWlR technology solutions are also optimized internally for layout, heat
transfer and component selection.

* Although, all of the dimcult 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. There are no concerns about unwanted shutdowns common to switching power supplies, if operated as specified. The iPOWlR 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.
