Note 1: Each of the four digital soft-start levels is tested for functionality; the steps are typically in 20mV increments.
Note 2: High duty-factor operation supports low input-to-output differential voltages, and is achieved at a lowered operating
frequency (see Overload and Dropout Operation section).
Note 3: MAX1630A/MAX1632A/MAX1633A/MAX1635A only.
Note 4: Off mode for the 12V linear regulator occurs when the SMPS that has flyback feedback (V DD ) steered to it is disabled. In
situations where the main outputs are being held up by external keep-alive supplies, turning off the 12OUT regulator pre-
vents a leakage path from the output-referred flyback winding, through the rectifier, and into V DD .
Note 5: Since the reference uses VL as its supply, the reference’s V+ line-regulation error is insignificant.
