The IR2161 is an 'intelligent' control IC specifically designed for electronic transformers that drive low voltage halogen lamps. All necessary features are integrated into a single 8-pin DIP or SOIC, says manufacturer International Rectifier. The IR2161 device can adapt to changing supply voltage, frequency conditions, and lamp conditions. It features a 600 V half-bridge driver, advanced overload and short-circuit protection circuitry with high temperature shutdown and adaptive control techniques. This offers a reliable alternative to traditional self-resonating, bipolar transistor half-bridge circuits. The IC also accommodates external dimming with a standard phase-cut, triac-based dimmer. Output drive capability is 250/400 mA, it has a 15,6 V zener diode clamp on Vcc, micropower start-up on less than 300 µA and has built-in 30-125 kHz oscillator.
