Intersil's sync buck regulator for broad range of apps

Intersil has released to market a new ISL8088, 800mA/channel dual step-down regulator with integrated power MOSFETs. This device operates from an input voltage of 2.7V to 5.5V and consumes 35microAmps quiescent current making it suitable for battery powered and other "Green Power" applications. The selectable operation between forced PWM mode and automatic PWM/PFM mode maximizes battery life.

Operating at a switching frequency up to 2.25MHz, this device provides internal digital soft-start and internal compensation. External synchronization capability up to 4MHz reduces beat frequencies in multiple IC systems. Independent enable and PowerGood signals for both channels are available. Protection features include peak current limiting, short circuit protection and thermal shutdown for reliable 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. In addition, it can be used in portable medical instrumentation and industrial process control systems, providing the benefits of low-cost, flexible operation, low-power and ultra-small footprint.

Price: $2.63 each in 1,000-piece units.
Availability: Now
