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

 

The IC is designed to work across 220 VAC. It may not adapt to 26 VAC.

Phase control is not hard with discrete components - http://www.sprags.com/building_a_simple_dimmer_circuit.html

 

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.
