+5Vsb is a standby output voltage that is always active whenever AC
power is present. +5Vsb supplies 1.0A current in normal operation and
is capable of withstanding maximum 10W (2 Amps) peak power for 10
seconds. +5Vsb provides a power source for circuits that must remain
operational when DC main output is in sleep/off state. +5Vsb over
current protection is built internal to its controller. 5Vsb OCP trip point is
set to be within 2.5A - 5A. 5Vsb OVP is clamp.
