International Rectifier Introduces Robust Self-Oscillating Electronic Ballast Lighting Control IC

International Rectifier, IR®(NYSE: IRF), a world leader in power management technology, has introduced the IRS2153D, an electronic ballast IC for fluorescent lamps. The new 600V self-oscillating half-bridge IC includes an internal bootstrap diode to simplify circuits. The new ballast IC is designed to increase efficiency and performance over older, less efficient self-oscillating bipolar transistor-based solutions. The IRS2153D has an oscillator frequency precision of 3%, which helps to optimize external component selection for uniform lamp brightness during manufacturing. A preheat feature, which sets the correct preheat frequency for the correct duration, helping to maximize lamp life, can be realized externally easily.

The IC is lead-free (PbF), and includes a 2V under-voltage lockout hysteresis for more robust ballast circuits and prevents unwanted shutdown if momentary transients occur. In addition, the new IRS2153D includes an under-voltage lockout circuit that ensures that the high-side floating voltage (VBS) correctly switches the high-side gate driver output (HO), protecting the external MOSFET.

The IRS2153D is made with IR’s proprietary high voltage integrated circuit (HVIC) technology, which is ideal for designing products to drive MOSFETs and IGBTs. The technology integrates a low-voltage driver with a high-voltage level shifter for high-side and low-side gate drivers in one monolithic IC.
