Quarter-Brick & Half-Brick (HE & HZ)
Pin Name Function
1   Vin(+)   Positive input voltage
2   ON/OFF   TTL input to turn converter on and off, referenced to Vin(–), with internal pull up.
3   Vin(–)   Negative input voltage
4   Vout(–)   Negative output voltage
5   SENSE(–)   Negative remote sense1
6   TRIM   Output voltage trim2
7   SENSE(+)   Positive remote sense3
8   Vout(+)   Positive output voltage
  Notes:
       1. SENSE(–) should be connected to Vout(–) either remotely or at the converter.
       2. Leave TRIM pin open for nominal output voltage.
       3. SENSE(+) should be connected to Vout(+) either remotely or at the converter.
