• Description: The Fifth Generation, Ultra Small Size, Isolated Dc-dc Converter
• Manufacturer: XP Power Limited

7-2 Adjustable Output Voltage
7-2-1 To lower the output voltage
BTA-S Series
Output Voltage : Vo[V]，Connecting resistor : Rb[kΩ]
BTAXX-03SXXX
BTAXX-05SXXX
BTAXX-12SXXX
BTAXX-12WXXX
Note : When adjusting the output voltage, please operate below max. power
Output voltage can be set as follow when Vadj pin and −Vout pin is short.
Please open this pin when not adjusting the output voltage.
Output voltage is adjustable by connecting resistor between Vadj pin and +Vout pin. (Or between Vadj pin and
−Vout pin)
Output voltage can be lowered by connecting resistor Rb between Adjustable Output Pin (Vadj) and Plus Output
Pin (+Vout). Calculation is as below. (Unit of Rb is [kΩ]).
DC-DC Converter
Vo = 1.26 × (91.5 + 2.62 Rb) / (39.6 + Rb)
Rb = (39.6 Vo − 115.3) / (3.30 − Vo)
Adjustable range is up to 3.15V.（Rb≧62）
Vo = 1.26 × (84.8 + 3.98 Rb) / (31.8 + Rb)
Rb = (31.8 Vo − 106.85) / (5.01 − Vo)
Adjustable range is up to 4.75V.（Rb≧160）
Vo = 1.26 × (201 + 9.53 Rb) / (57 + Rb)
Rb = (57 Vo − 253.26) / (12.01 − Vo)
Adjustable range is up to 11.4V.（Rb≧620）
Vo = {1.26 × (429 + 19.1 Rb) / (103 + Rb)} / 2
Rb = (206 Vo − 540.54) / (24.07 − 2 Vo)
Adjustable range is up to ±11.4V. (Rb≧1500)
