Ballast boosts lamp efficiency and
performance
A new electronic ballast IC for fluorescent lamps is designed to increase efficiency and performance over older, less efficient self-oscillating bipolar transistor-based solutions.
International Rectifier has introduced the IRS2153D, an electronic ballast IC for fluorescent lamps The new lead-free (PbF) 600V self-oscillating half-bridge IC includes an internal bootstrap diode to simplify circuits

MOSFETs improve 12V-input converter efficiency
Two new 20V HEXFET power MOSFET families from International Rectifier are designed to increase efficiency by up to 4% in 12V-input DC/DC convertors.
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 optimise external component selection for uniform lamp brightness during manufacturing.
A preheat feature, which sets the correct preheat frequency for the correct duration, helping to maximise lamp life, can be realised externally easily.
The IC includes a 2V undervoltage lockout hysteresis for more robust ballast circuits and prevents unwanted shutdown if momentary transients occur.
In addition, the new IRS2153D includes an undervoltage lockout circuit that ensures that the high-side floating voltage correctly switches the high-side gate driver output, protecting the external MOSFET.
The new IRS2153D is based on the very popular IR2153x product family that integrates a "555" type oscillator circuit with a 600V half-bridge gate driver to drive two output FETs or IGBTs.
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.
Gate drive outputs are designed using a latch-immune CMOS circuit.
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.
The IRS2153DPbF, IRS2153DSPbF and IRS2153DSTRPbF are available either in tubes or tape and reel.
Devices are lead-free and compliant with the Restriction of Hazardous Substances Directive (RoHS).
