Referece datasheet : DDA002C Datasheet.
The DDA002C controller hosts a high performance circuitry dedicated to driving halfâbridge topologies, such as lamp ballasts for backlighting applications or resonant converters like the LLC circuit. The controller includes everything needed to build a reliable and rugged converter, including a preâheating period and various protections such as an adjustable brownâout, for instance. Both, minimum and maximum switching frequencies, are adjustable by single pull down resistor, offering the ability to operate between 30 kHz and 500 kHz.
