The Microchip Technology HV852K7-G is a high-voltage, low-noise, inductorless EL (electroluminescent) lamp driver. It is designed to drive EL lamps with capacitive values up to 5.3nF, suitable for approximately 1.5in² lamp sizes.
This driver converts a low voltage DC input, ranging from 2.4V to 5.0V, to a high voltage AC output across an EL lamp. It utilizes a charge pump scheme, eliminating the need for external inductors, diodes, and high-voltage capacitors commonly found in conventional topologies. The device features output voltage regulation and an enable function for dimming capabilities.
The HV852K7-G operates within a temperature range of -25°C to 85°C and supports EL lamp frequencies from 50Hz to 500Hz. It is available in a 10-DFN (3x3mm) surface-mount package, specifically a 10-WFDFN Exposed Pad, supplied on a reel.
Key applications include cellular phone keypads, watches, small handheld wireless devices, and MP3 players, where compact and efficient EL backlighting is required.
