This datasheet provides detailed information on the features and characteristics of the MIC4830 low noise 180Vp-p EL driver.
The MIC4830 is a low‑noise 180 Vpp electroluminescent (EL) lamp driver that integrates a high‑voltage boost converter and an H‑bridge driver. It is designed for backlighting EL panels in mobile phones, multimedia players, automotive electronics, and other applications where compact, high‑voltage illumination is required.
Key features include a wide input voltage range (1.8 V‑5.5 V), adjustable lamp and boost‑converter frequencies via external resistors, very low operating current (45 µA typical, 10 nA shutdown), and availability in 3 mm × 3 mm MLF and MSOP‑8 RoHS‑compliant packages.
