High efficiency, ultra small size adjustable output type high voltage power supply High efficiency, I type resonance PWM formula 3.5W high voltage DC-DC converter 0V to 350V PHV Series The PHV series was built using Bellnixs independent technology, the I type resonance PWM formula. With the use of I type resonance PWM formula, high efficiency (68% typ.) has been achieved with the high voltage power supply. As a result, the dimensions are 1/5 of the normal product size with the existing power of 3.5W. The PHV series is also using the 5 sided metallic shield case, and is expected to have high reliability and long life for an high voltage DC-DC converter with adjustable output voltage. ■ Features ･High efficiency 68%typ. ･5 sided metallic shield ･PCB mount type ･High reliability ･ON/OFF control (option) ･MTBF anticipated value 400､000H ･Max output capacity 3.5W ･Adjustable voltage with external voltage ･Over current protection ･Low price/long life ･Ultra small size ･Low ripple noise ■ Model name/Rating Model name PHV Series PHV12-350S10P PHV12-350S10N Input voltage (Vdc) Output voltage (Vdc) Adjustable output voltage range (Vdc)(Note1) 10.8 to 16.5 10.8 to 16.5 +350 -350 0 to +350 Output current (mA) 0 to 10 0 to 10 0 to -350 Output capacity (W) 3.5 3.5 Input current (mA) typ Ripple noise (mVp-p) typ Case 430 100 100 PH-15 PH-15 430 ■ Specifications Line Regulation 0.01% typ.(Input voltage +12V±1V) Load Regulation 0.01% typ.(Load current varying from 0％ to 100％） Temp Regulation Over current protection ±0.01%/℃ typ.(Temp varying from -10℃ to +50℃) Drooping type characteristic, auto restart circuit which operates at 105% or greater Output voltage acc.

When mounting to to a double-sided PCB, the wiring for the converter be should be on the soldering side. AlsAlso, this converter will generate high voltages so the crecreepage distance should also be taken in when whdesigning. ② When mounting to a double-sided PCB, the land of ou the parts side of the high voltage output pin should ③ The metallic case does not need to be connect to ground. HoHowever, when using and gound with the metallic case, ca make the impedance lower as possible between the ground. The PHV series output voltage can be adjusted by using an external voltage or external adjustable resistor. 1 Vout (+ or -) ＋Vin 7 + 12V SW1 Open=ON Short=OFF C1 PHV 2 SW1 Vin Com Load C2 Vout Com 6 ON/OFF Vref Vcont C1=22 to 47μF C2=0.047 to 0.1μF 4 3 5 (OPEN) + Output voltage control (Apply 0V to 6V) ■ Vref pin (Standard voltage output) When controlling the output voltage with an adjustable resistor, this pin is used. Vref has a standard output voltage of 6V. In this case, the external adjustable resistor is 5KΩ. Since the resistance value from the external adjustable resistor will decide the output voltage with the effect of the specified value, use a resistance value with an accuracy of 5KΩ±5%. The type of resistor does not matter, as long as it is 5KΩ, however one with a good temp coefficient is recommended. Standard voltage generation circuit Vref 4 PHV series When lowering the output noise, the wiring of the input and output should be as short as possible. Place C2 closest to the load, paying attention to creepage and clearance distances. Point! ① Choose a capacitor with a high-frequency when adding to the input. ② Earth (COMMON) line should be thick and short in the pattern design to lower the common impedance. Vout Com 6 ③ The capacitor which is connected to the output side should be able to withstand the pressure, when connected to the load side. At this time, the capacitor lead should be shortened. Also when the load response time is a problem, Vcont 3 External adjustable resistor (5.0KΩ) ■ Prevention of inverse input connection please be aware of the time constant.
