Detailed Description
1.
Standby Switch (pin 4)
The power supply can be turned on or off via
pin 4 (Stby). The threshold voltage of pin 4 is
set at about 3 VBE (typ.). The power supply
current is about 0.01
A (typ.) in the standby
state.

pin 4 is changed.
Benefits of the Standby Switch
(1)
VCC can be directly turned on or off by a microcontroller, eliminating the need for a switching relay.
(2)
Since the control current is minuscule, a low-current-rated switching relay can be used.
