Power Good Output
The PGood signal is an open drain output requiring a user’s external pullup
resistor to +5V or less referred to -Vin. PGood indicates when the converter
has stabilized and the output is approximately within regulation. PGood is
TRUE (open drain, high impedance state) if the converter’s power output
voltage within about +/-10% of the setpoint. When PGood is FALSE (satu-
rated low impedance state, LOW), the output resides within about +0.4V or
less referred to -Vin, depending on the pullup current.
tion. However, gross overcurrent or output short circuit will set PGood to
FALSE (less than +0.4V saturation, low impedance condition). Because of
the open drain design, several converters may connect their PGood’s in
parallel with a common external pullup resistor in a wired-OR method.
approximates a forward-biased diode to ground.
small signal FET inside the PWM. Use electrostatic protection. The PWM
may be destroyed by inadvertant static discharge or excess current into
the PGood signal. Pull down current should be limited to 5 mA maximum
and the external pullup voltage should never exceed +5V referred to the
negative input, -Vin.
Note that PGood does not directly measure an output overcurrent condi-
The following conditions will render PGood as FALSE (Low):
+Vout is greater than 10% error from Vset.
Softstart is active and not yet complete.
An input undervoltage is present at +Vin.
An output short circuit has occurred.
An over temperature (OT) condition has occurred.
At power up, before the converter has achieved stable regulation, PGood
