Overview
The LA5663V is Phase Control Voltage Inverter Control IC.

Functions
• Phase control technique allows the voltage transformer to be driven at a frequency that provides excellent efficiency.
• The phase can be adjusted with an external resistor.
• Allows burst adjustment.
• Full complement of built-in protection circuits, including over-voltage protection and tube current detection and protection.
• High-precision reference voltage system. VREM precision: ±1%
• The on/off state of the VREM circuit can be controlled independent.
