? Filament Lamp is a Resistive Load
? No Preheat / Ignition is required
? DC Bus is full wave rectified line without smoothing
? Close to Unity Power Factor is inherent in system
? Can be dimmed with Triac (standard domestic type) dimmer
? Dimming is achieved by PHASE CUTTING of the AC line
? Output is isolated Low Voltage
? Protection required against output short circuit or overload not open circuit.
? Shutdown must be Auto-Resetting
The protection circuitry is auto-resetting so that if the output is short circuited the system will
periodically try to restart and then shut down again. When the short-circuit is removed the lamp will
be able to come back on again without the need for cycling the AC supply off and back on again to
reset. The external capacitor at the CSD pin is used in several different operating modes allowing
the IC to be limited to 8 pins. The CSD pin is connected to different circuit blocks during different
modes, controlled by internal control logic.
The current sense (CS) input is connected to the voltage compensation and shutdown circuit blocks.
The CSD capacitor is switched between different circuits through internal transmission gates. The
oscillator is voltage controlled and its input is connected to the CSD capacitor during normal opera-
tion. In case of overtemperature or external shutdown, the IC will go into a fault mode. In this mode
the IC is in latched shutdown and will restart only after resetting the mains. In case of overvoltage or
overload, the IC will go into a auto-resetting fault.
The different modes of operation of the IC and the system implications are described here:

Supplying VCC to the IR2161
The under-voltage lockout mode (UVLO) is defined as the state the IC is in when VCC is below the
turn-on threshold of the IC. To identify the different modes of the IC, refer to the State Diagram
shown in the IR2161 data sheet. The IR2161 under voltage lock-out is designed to maintain an ultra
low supply current under 300uA and to guarantee the IC is fully functional before the high and low
side output drivers are activated.
The capacitor (CVCC) is charged by current through supply resistor (RS) minus the start-up current
drawn by the IC. This resistor charges CVCC to the UVLO+ threshold, at which point the IR2161
starts to operate and the LO and HO outputs become active. In a Halogen convertor it is important
to consider that the DC bus is completely unsmoothed and has a full wave rectified shape. CVCC
should be large enough to hold the voltage at VCC above the UVLO threshold for one half cycle of
the line voltage as it will only be charged at the peak. A charge pump consisting of CSNUB con-
