_______________________________________________________________________________________
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 Operationsection).
Note 3:
MAX1630/MAX1632/MAX1633/MAX1635 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.
