IR Presents New IR2167 Ballast Controller

International Rectifier Corp. (IR, El Segundo, CA) introduced a single-chip, fluorescent, lamp ballast device with an active, critical conduction mode, boost-type power factor correction (PFC) method. the IR2167, which controls the entire electronic ballast, and combines lamp control, PFC and a 600V half-bridge driver.

The ballast control section in the IR2167 incorporates a programmable oscillator, which enables all ballast operating frequencies and MOSFET driver output deadtime. The lamp protection circuitry shuts down when any external lamp fault condition is detected.

The IR2167 is designed to simplify PFC ballast circuits and improve efficiency while maximizing lamp life. The IR2167 enables ballast designs with power factors of 0.99, and THD lower than 10%, well within the IEC 6100-3-2 standards.

The new IR2167 is available immediately. Pricing for the IR2167S in a 20-pin DIP is $2.38 each, and the IR2167 in a 20-pin SOIC is $2.68 each, both in 10,000-unit quantities.
