The device delivers up to 3A and is available in a 3.5 x 3.5mm package. IR says efficiencies in excess of 97.5% are obtainable for designs converting power from a 6V input to a 4.8V output.
The IR3823 also allows switching at up to 1.5MHz from a 12V supply. Featuring constant frequency and virtually jitter free operation, it is well suited to noise sensitive applications, while the higher bandwidth reduces component count to shrink pcb footprint.
