This document introduces the features of TDK CXA-P1212A-WJL DC to AC Inverters, including one-connector, two-output design, two 4W lamp outputs, PMW dimming circuit, overcurrent protection circuit and illumination stabilization circuit.
The CXA‑P1212A‑WJL inverter provides a one‑connector, two‑output design optimized for thin LCD panels and cold‑cathode lamps. It delivers two 4 W lamp outputs (8 W total) and features a PMW circuit that enables wide‑range dimming via voltage or resistance control, plus built‑in over‑current and illumination‑stabilization circuits.
Typical applications include back‑lighting for 6‑12‑inch LCD displays, computer touch panels, medical devices, ATMs, POS terminals, telecom equipment, microscope monitors, and arcade machines. The device operates from 10.8 V to 13.2 V input, tolerates temperatures from –10 °C to +70 °C, and weighs about 20 g.
