Power supply for MPPC® C14156 Bias power supply with built-in temperature compensation function for MPPC The C14156 is a high voltage power supply that is optimized for driving MPPCs (multi-pixel photon counters). Up to 80 V can be output by applying a control voltage and supply voltage. It contains a temperature compensation function that constantly optimizes the MPPC operation even in environments with varying temperatures. Wide output voltage range: 0 V to 80 V Driving MPPCs With a temperature compensation function With an ON/OFF control function Output voltage adjustment using a control voltage Compact, surface mount type Absolute maximum ratings Parameter Supply voltage Control voltage Setting voltage of the output voltage temperature coefficient ON/OFF control voltage Operating temperature Storage temperature Reflow soldering conditions*2 0 to Vs -20 to +60 -30 to +85 Peak temperature: 240 °C, 3 times (see P.5) Vtcr SHDN Topr Tstg Tsol *1: When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. *2: JEDEC level4 Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings. Recommended operating conditions Parameter Supply voltage Control voltage Electrical characteristics (Typ.

Power supply for MPPC Function Connect to an analog temperature sensor. If you do not use the temperature compensation function (not connecting a temperature sensor), insert a 1 kΩ resistor between pin no.1 and GND. Output voltage ON/OFF control No connection These pins should not be connected to any terminals. High voltage output Reference voltage output Output voltage temperature coefficient control Positive supply voltage Connect a bypass capacitor between this pin and ground. Connect the capacitor as close to this pin as possible. Ground Connect directly to the ground plane using the shortest...

Power supply for MPPC Recommended land pattern (unit: mm) Vref Vtcr * To change the temperature coefficient, apply an external voltage to the Vtcr terminal or connect a potentiometer between the terminal and the Vref terminal. KACCC0912EA Note: For the analog temperature sensor, use an LP731JTTE102F3600 by KOA. If you do not use the temperature compensation function (not connecting a temperature sensor), insert a 1 kΩ resistor between pin no.1 and GND.
