Abstract: SMPS losses consist of
switching loss, conduction loss, and core loss.
But, in case of light load the switching loss takes
the most things in SMPS, and then the max
currents should be limited to decrease audible
noise. Consequently, to increase the efficiency
of the SMPS at light load, the low switching
frequency and the current limit of the SMPS
have the good effect for low power consumption.
This paper describes a novel two kinds of burst
mode operation. They show how to implement
the burst mode through the feedback pin without
additional parts in SMPS device.
