iP1203 Power Block
Description
The iP1203 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.
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.
