Intersil’s latest five highly integrated synchronous buck regulators step-down 5V rails to point-of-load (POL) inputs as low as 0.6V for FPGAs, DSPs, and microprocessors. The ISL8018 delivers up to 8A of continuous output current from a 2.7V to 5.5V input supply, while offering up to 97% efficiency. The 2 x 2mm ISL8003x family of devices delivers up to 3A of continuous output current from a 2.7V to 5.5V input supply and offers up to 95% peak efficiency for delivering general POL conversions in telecom, cloud computing, industrial, instrumentation and medical equipment. The ISL8018 also provides an innovative SYNCIN and SYNCOUT feature that connects and synchronizes multiple regulators at the same switching frequency in a master/slave configuration using a phase shifting time delay. Using an integrated VSET feature, the voltage output margining can be set at ±10% to compensate for output voltage IR drop. The ISET feature provides programmable output current limits to support 8A, 5A and 3A applications. In addition, the ISL8018’s programmable switching frequency from 500 kHz up to 4MHz enables the use of smaller passive components.
The ISL8018 8A synchronous buck regulator is available in a 3 mm x 4 mm, 20-lead QFN package priced at $1.60 each/1,000. For more information, visit http://www.intersil.com/products/isl8018
The ISL80030, ISL80030A, ISL80031 and ISL80031A 3A synchronous buck regulators are available in 2 mm x 2 mm, 8-pin DFN packages. Pricing for the ISL80030 and ISL80030A is 0.59 each/1,000, and the ISL80031 and ISL80031A is $0.60 each/1,000. For more information, visit http://www.intersil.com/products/isl80030
