PBL 380 85 July 1999 PBL 380 85 Integrated circuit for transformerless driving of battery powered EL (electroluminicent) lamps Description. PBL 380 85 is a monolithic integrated circuit for supplying power to an EL (electroluminicent) lamp. This is intended to replace the LCD background illumination system in battery powered handheld equipment with a low power EL- lamp. Especially suitable for mobile phones where current saving is highly important, as background illumination for both LCD and keyboard. Output voltage max. 190V, min. 170V at max. 2mA constant current charge / discharge of the EL- lamp. Application dependent parameters such as charge / discharge current are set by an...
