HALOGEN CONVERTOR CONTROL IC
Typical Connections
IR2161(S) & (PbF)
Description
The IR2161 is a dedicated Intelligent Half bridge Driver IC for a Halogen convertor (electronic transformer). It
includes all necessary protection features and also allows the Convertor to be dimmed externally with a
standard phase cut dimmer with both leading or trailing edge types. This IC provides the advantage of reduced
thermal stress in the lamp due to softstart. There is also compensation of the output voltage for load regulation.
It enables the convertor to operate with extremely low harmonic distortion over the full range of loads. The
IR2161 includes adaptive deadtime to allow cool running MOSFETs and improves the EMI behaviour due to
frequency modulation (dither). All the features are integrated in a small 8 pin DIP/SOIC package to allow for a
size reduction in the next generation of convertors.

Note 1: This IC contains a zener clamp structure between the chip V
CC
and COM which has a nominal breakdown
voltage of 15.6V. Please note that this supply pin should not be driven by a DC, low impedance power source
greater than the V
CLAMP
specified in the Electrical Characteristics section.
Note 2: Enough current should be supplied into the V
CC
pin to keep the internal 15.6V zener clamp diode on this pin
regulating its voltage, V
CLAMP
.
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters
are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power
dissipation ratings are measured under board mounted and still air conditions.
