IR introduces the electronic ballast IC IRS2153D for fluorescent lamps. This new 600V self-oscillating half-bridge IC includes an internal boost diode to simplify the circuit. The new ballast IC is designed to increase efficiency and performance. The efficiency of the self-oscillating bipolar transistor solution is low. The IRS2153D's oscillator frequency accuracy is 3%, which helps to optimize the selection of external components for uniform lamp brightness during manufacturing. Its preheating characteristics are set. The correct preheat frequency helps maximize lamp life, which is extremely easy to implement. The IC is lead-free and contains a 2V undervoltage lockout hysteresis to get a robust ballast circuit that prevents In addition, the new IRS2153D includes an undervoltage lockout circuit to ensure that the high-side floating voltage (VBS) correctly switches the high-side gate driver output (HO), thus protecting the external connection. MOSFET. The new IRS2153D is based on the popular IR2153x product family, which integrates a 555-type oscillating circuit with a 600V half-bridge gate driver to drive two output FETs or IGBTs. The IRS2153D is powered by IR. Integrated electricity Road (HVIC) technology, which is ideal for designing products that drive MOSFETs and IGBTs. The gate drive output is designed with a latch-up immune CMOS circuit. This technology integrates a low voltage driver with a high voltage level shifter for use in a single High-side and low-side gate drivers on the IC. The following table shows its performance specifications:
The IRS2153DPbF, IRS2153DSPbF and IRS2153DSTRPbF.10K quantities are now available at $0.80. The device is lead-free and RoHS compliant.
