New High Efficiency 8A and 3A DC/DC Converters
ISL8018 DC/DC Converter
Intersil's new ISL8018 and ISL80030/30A/31/31A sync buck regulators step-down 5V rails to point-of-load (POL) inputs as low as 0.6V for FPGAs, DSPs and microprocessors.

The feature-rich ISL8018 8A DC/DC converter offers up to 97% efficiency and higher integration than competitive devices:
Complete converter occupies less than 97mm² of board space
±10% output voltage margining
Adjustable switching frequency from 500kHz to 4MHz; default at 1MHz
The 2 x 2mm ISL8003x 3A devices are pin-compatible and offer up to 95% efficiency:
Switching frequency up to 2MHz
Provides quiescent current as low as 35μA
Selectable PFM or PWM operation
