Switch Tricks Electronic Ballast ICs Into Working On Low Voltages
Ballast-control ICs from International Rectifier and other similar half-bridge gate drivers feature an undervoltage lockout (UVLO) on the high-side output. This function protects the driven MOSFETs or insulated gate bipolar transistors (IGBTs) in the event that VB drops to potentially dangerous low levels. When designing an electronic ballast for operation off a 12-V dc (10.5 V to 13.6 V) battery, however, the UVLO creates a challenge ...
