The SP4415 is a DC-AC converter from Sipex Corporation. It can convert input voltage as low as 2.2V to any of four AC voltage levels which can be set via external switch. It features high impedance clock input and signal conditioner, and requires only one external inductor.
The SP4415 is an integrated circuit designed to drive electroluminescent (EL) lamps from low-voltage battery sources. It converts DC input voltages as low as 2.2V into four selectable AC voltage levels, allowing for adjustable brightness on EL backlit displays.
The device requires only one external inductor and operates with a high-impedance clock input suitable for direct connection to crystal oscillators. It is optimized for applications such as watches, pagers, and other battery-powered devices requiring efficient backlighting.
