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.

Description

iP1201PbF Power Block

Features

* 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. There are no concerns about unwanted shutdowns common to switching power supplies, if operated as specified. 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.
