bsv-1.5s12r0h XP Power Limited, bsv-1.5s12r0h Datasheet - Page 7

• Manufacturer Part Number: bsv-1.5s12r0h
• Description: Pol Dc-dc Converter
• Manufacturer: XP Power Limited

When using at 1.5V without adjusting output voltage, keep Trim pin (7pin) open. By connecting a resistor between Trim pin (7pin) and -Sense pin,
the output voltage can be adjusted within the range of 0.6-1.5V. Connect -Sense pin to GND (5pin)
When adjusting the output voltage, place the Rx close to the converter and make the wiring of Rx as short as possible. If the Trim pin catches
noise, malfunction may occur.
To calculate the external resistance, please refer to the equation below. After calculating the external resistance, please check the output voltage
and adjust the resistance value.

8-3. Adjusting Output Voltage
Bellnix DC-DC CONVERTERS
By using the ON/ OFF control function, ON/ OFF of the output without connecting and disconnecting the input can be controlled.
ON/OFF Pin (9pin) has been connected with +Vin terminal internally by the resistance of 47kΩ.
When not using the ON/ OFF control, keep the ON/ OFF pin open.
