7-3 Output Over Current Protection Function
7-4 Low Input Voltage Protection Function
7-2-2 To raise the output voltage
BTA-S Series
Output Voltage : Vo[V]，Connecting resistor : Ra[kΩ]
BTAXX-03SXXX
BTAXX-05SXXX
BTAXX-12SXXX
BTAXX-12WXXX
Output voltage will be lowered when output current is in state of over current and start operating over current
protection circuit. (Over current protection set point : 105 to 250% of rating current value)
It will automatically recover when over current state is released. In order to avoid from damage, please do not hold
the over current state for more than 30sec.
If by any reason does not auto recover after releasing, please off the output at ON/OFF control or switch off to
reactivate.
This product builds in low input voltage protection function to avoid malfunction at low input voltage. Commencing
operation and termination voltage range is within the below table.
Output voltage can be raised by connecting resistor Ra between Adjustable Output Pin (Vadj) and Minus Output
Pin (−Vout). (Unit for Ra is[kΩ])
DC-DC Converter
Vo = 1.26 × (91.5 + 2.62 Ra) / (32 + Ra)
Ra = (115.3 − 32 Vo) / (Vo − 3.30)
Vo = 1.26 × (84.8 + 3.98 Ra) / (17.8 + Ra)
Ra = (106.85 − 17.8 Vo) / (Vo − 5.01)
Vo = 1.26 × (201 + 9.53 Ra) / (16.9 + Ra)
Ra = (253.26 − 16.9 Vo) / (Vo − 12.01)
Vo = {1.26 × (429 + 19.1 Ra) / (18 + Ra)} / 2
Ra = (540.54 − 36 Vo) / (2 Vo − 24.07)
