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.  
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.
