    Hi there is it possible that someone can help me with the above Phase control IC.I'm encountering some problems with the Application example - Triac Control for up to 50mA Gate Trigger Current.I've reduce the AC voltage to 26V AC too suit my circuitry,which drives a 24V 150W halogen lamp.With this I changed some resistors for eg Rsync is 27K and the input resistor is 390 ohm and also changed the TXC10M60 with a common used TIC225M triac.
    No luck with the circuit.Help please

    Hello,

    Can you post the schematic of what you have now?
    I think it must be possible to let it run at your 26 Volts AC.
