Product Summary

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.
