Measuring 2 x 2 mm, Intersil ISL8003x Series delivers up to 3 A of continuous output current from 2.7–5.5 V input supply and offers up to 95% peak efficiency for delivering general POL conversions in telecom, cloud computing, industrial, instrumentation, and medical equipment. Synchronous buck regulators step down 5 V rails to POL inputs and are as low as 0.6 V for FPGAs, DSPs, and microprocessors. Pin-compatible devices integrate very low RDS(ON) high side PMOS and low side NMOS MOSFETs.
