Switching section power-good signal
The SPG pin is an open drain output used to monitor output voltage through VSNS (in fixed
output voltage mode) or V
the soft-start timer has expired. The SPG signal is held low if the output voltage drops 10 %
below or rises 10 % above the nominal regulated value. The SPG output can sink current up
to 4 mA.
Switching section output discharge
Active soft-end of the output occurs when the SWEN (SWitching ENable) is forced low.
When the switching section is turned off, an internal 25 Ω resistor discharges the output
through the VSNS pin.
