Working principle

The operation of the LTC3835EUFD#TRPBF is based on a concept known as phase-shifted full-bridge switching DC/DC controller. The phase-shifted full-bridge switching utilizes multiple phases such that the power distribution is spread out over multiple switching phases. This increases the stability of output voltage, reduces the output ripple and prevents current peak and dynamic loss. The chip also has the ability to alternate between burst mode operation and forced continuous mode to optimize efficiency in accordance to the load condition, adjusting the on-time for maximum efficiency and minimizing dynamic loss.
