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.
iPOWIRtechnology 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.
