The ISL8088 is an 800mA/channel dual step-down regulator with integrated power MOSFETs. The 2.7V to 5.5V input voltage range and 35microA quiescent current make the ISL8088 suitable for battery powered and other green power applications.
The selectable operation between forced PWM mode and automatic PWM/PFM mode maximizes battery life, the company claimed.
ISL8088 features a switching frequency as high as 2.25MHz, along with internal digital soft-start and internal compensation and can reduce total component count, cost and overall size for a wide range of applications, the company added.
External synchronization capability up to 4MHz reduces beat frequencies in multiple IC systems. Independent Enable and PowerGood signals for both channels provide inherent sequencing capability in a multi-chip system.
Protection features include peak current limiting, short circuit protection and thermal shutdown for operation under adverse conditions.
The ISL8088 is designed for a wide range of products including digital cameras, personal media players, printers, copiers, storage drives, LCD-TVs, set-top boxes, graphics cards and automotive applications.
