Highly integrated boost regulator

11 July 2007 Power Electronics / Power Management

Providing a complete boost regulation solution for passive matrix OLEDs (organic light emitting diodes), Intersil has released the ISL97701. The device's distinguishing characteristic is its high level of integration, incorporating a Schottky diode and fault protection. The integration of the Schottky diode reduces the BOM cost and saves board space, while an integrated input disconnect switch protects the device against over-current, over-voltage and over-temperature conditions. With efficiency up to 87%, it can provide output up to 28 V, and can deliver 50 mA at 18 V. The output is set via external resistors. Measuring 3 mm x 3 mm x 0,9 mm in a 10-lead DFN package, this is a very compact power management IC ideal for portable applications.
