PRODUCTION DATA
At the beginning of soft start, the converter operates in discontinuous conduction mode (DCM) for the first 16 PWM cycles. During this time, a zero-cross detect comparator is used to turn off the low-side MOSFET when the current reaches zero amps, preventing the discharge of any prebiased conditions on the output. After the 16 cycles of DCM, the converter enters FCCM mode for the remainder of start-up and into regulation.
