Abstract :
Digital burst mode is an operation that can be used to control power transistor switching by the microprocessor signal. This also allows burst mode to be extended to future applications, such as multiple regulation in TV and other audio/video products. This technique substantially reduces stress for the main switching transistor during standby mode since it is not a complete turn-off.
