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 ¥Low ripple noise ¥Ultra small size ¡Model name/Rating ¡Specifications Note1: The output voltage will be controlled by applying the Vcont voltage. Using an adjustable resistor or an external voltage, voltage should be applied on the Vcont pin in order to control the output voltage. When Vcont voltage=0V the output voltage (output residual voltage) should be less than 2.0% of the max output voltage. Note2: The ON/OFF control is optional. When ordering, add a suffix "R" to the end of the product name. Ex) PHV12-350S10PR.

¡ Standard usage information ¡Setting/Adjusting the output voltage PHV series The PHV series output voltage can be set or adjusted using an external voltage or external adjustable resistor. The PHV series does not require any external parts, however when the input impedance is high, for example: the distance between the power supply and converter is long, the input line is thin, or the input side has a filter then connecting a capacitor C1 to the input side is recommended. Place the capacitor as close as possible to the converter pin side, to lower the lead inductance. ¡ ON/OFF control (optional) By opening and closing between the ON/OFF pin and Vin Com pin the output voltage can be externally turned on and off. Between the ON/OFF pin (5) and -Vin pin (2) @@@@The ON/OFF pin is internally pulled up to the 5V, so be careful @@@@of the voltage from the switching element of the ON/OFF pin (photo couplers, transistors, etc) Keep open when not using the ON/OFF control. Since the chattering to the ON/OFF pin will affect the output voltage, choose one without any chattering. When the output is turned off by the ON/OFF control, the residual output voltage should be within 0.5%. (at Input/Output rating) The above characteristics (Output voltage -VR resistor value ¡ Over current protection characteristic) graph is an indication of the resistance value R1 and R2. When setting the voltage to a set rate using The PHV series has a over load and load short a stable resistor, first decide the adjustable resistor R1 and R2. protection installed. When the Do not apply voltage higher than 6V+5% on the Vcont. product status is in over load or load short mode, the Use an adjustable resistor appliance with good temperature output voltage will decrease, and once the problem characteristics. has been removed, the voltage will automatically recover. When the resistance value is 5.0KΩ(R1=0Ω, R2=5KΩ), the max.voltage 6.0V will impress to Vcont pin. Therefore, the margin of error for the resistance value will largely affect the max output voltage, so use the resistance value as 5.0KΩ±5%.

¡Recommended pattern ¡Lowering the output noise even farther @The PHV series uses a metallic case. When mounting The PHV series output voltage can be adjusted by using an to to a double-sided PCB, the wiring for the converter external voltage or external adjustable resistor. b e should be on the soldering side. AlsAlso, this converter will generate high voltages so the cr ecreepage distance should also be taken in when whdesigning. AWhen mounting to a double-sided PCB, the land of ou the parts side of the high voltage output pin should BThe 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. ¡Vref pin (Standard voltage output) When controlling the output voltage with an adjustable resistor, When lowering the output noise, the wiring of the input this pin is used. Vref has a standard output voltage of 6V. and output should be as short as possible. Place C2 In this case, the external adjustable resistor is 5KΩ. closest to the load, paying attention to creepage and Since the resistance value from the external adjustable resistor clearance distances. 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. @ Choose a capacitor with a high-frequency when adding to the input. A Earth (COMMON) line should be thick and short in the pattern design to lower the common impedance. B 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, ¡Prevention of inverse input connection please be aware of the time constant. The converter may break if the polarities are reversed. If there is a possibility in which the connections maybe reversed, connect a diode and fuse like below. ¡Guarantee This product shall be guaranteed for a year.
