Intersil's ISL97701 OLED boost regulator

Intersil Corp. has announced the release of the ISL97701 chip. By combining high current output, an integrated Schottky diode and fault protection, Intersil provides the industry's most complete boost regulation solution for passive matrix OLEDs (PMOLEDs).

With efficiency up to 87 percent, ISL97701 can deliver 50mA of output current at 18V. It can provide up to 28V output, enabling power efficient operations in MP3, PMPs, automotive clustering and low-end cellphones PMOLED displays. ISL97701 is also suitable for standard boost regulation applications such as WiMAX card and LCD bias generator power applications.

The integration of the Schottky diode reduces the BOM cost and saves board space, while an integrated input disconnect switch protects the device against overcurrent, overvoltage and over temperature.

ISL97701 is highly versatile with a variable output that can be set by external resistors to match the needs of the application. At just 3-by-3-by-0.9mm, its 10-lead DFN (Pb free) package is a very compact power management IC for portable apps.

The advantage that Intersil's ISL97701 offers over similar competing devices is its combination of features. Customers no longer have to choose between high current output and fault protection, or fault protection and an integrated Schottky diode. Along with its ISL97702, Intersil provides a solution that delivers all of these features. ISL97702 is recommended for customers who need to dynamically adjust two levels of output voltages.

The ISL97701 OLED boost regulator is now available.
