Description：
The iP1001 is a fully optimized solution for high current synchronous buck applications requiring up to 20A. The iP1001 is optimized for single-phase applications, and includes a full function fast transient response PWM control, with an optimized power semiconductor chip-set and associated passives, achieving benchmark power density. Very few external components are required, including output inductor, input & output capacitors. Further range of operation to 3.3Vin can be achieved with the addition of a simple external boost circuit, and operation up to 3.3Vout can be achieved with a simple external voltage divider.
iPOWIR technology offers designers an innovative board 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.
