Epson Power Conversion has introduced the EPC9115 demo board, which supports an input voltage range of 48 V to 60 V and is turned to 12 V with 42 A output current. It uses EPC2020 (60 V) and EPC2021 (80 V) enhanced gallium nitride (eGaN?) power transistors, Texas Instruments' LM5113 half-bridge driver and UCC27611 low-side driver. The power stage uses a conventional hard-switch and an isolated buck converter with a 300kHz switching frequency. 1/4 brick performance in an industry standard 1/8 brick format The entire converter can be placed in a 1/8 brick size, except that the EPC9115 demo board is specifically sized to allow for connection and bench evaluation. The design includes individual holes to help design engineers easily perform simple waveform measurements and computational efficiency. The EPC9115 uses a full-bridge primary power stage, 4:1 transformer, center-tap output stage with an active reset buffer and uses the Microchip dsPIC? family of controllers and basic voltage mode control. Compared to other commercial devices of the same type, the EPC9115 can operate at 300 kHz with a switching frequency of 50% to 100% higher. Alex Lidow, co-founder and CEO of Epson Power Conversion, said: "The EPC9115 demo board delivers 500 W DC/DC converter performance in an industry-standard 1/8 brick converter size. eGaN FETs drive industry adoption This unprecedented power density." The EPC9115 demo board is priced at $812.50 and can be purchased online at Digikey: http://?lang=en. The so-called portable projector, also known as pocket projector, mainly through the 3M LCOS RGB three-color projector and decoding technology, the traditional huge projector is compact and portable, making the projection technology closer to life and entertainment. portable projector mini,portable projector 1080p,portable projector camping,portable projector with speakers,portable projector for camping Shenzhen Happybate Trading Co.,LTD , https://www.happybateprojector.com
Advantages compared with traditional projectors:
1. Small size, light weight, easy to carry.
2. Low calorific value and low noise.
3. The price is relatively cheap.
4. Most models support wireless connection through software projection.
Applicable fields:
1. Replace some functions of TV: some machines can have built-in CMMB function, or can be directly connected to the set-top box to put TV, which can be used as a 21-inch TV during the day and a 60-100-inch TV at night (Note: Because of lumen and resolution issues, lumens during the day If the degree is not enough, it must be projected at a close distance) to achieve the effect of home theater; it is convenient to move and break through the traditional film and television space. Even if you are on the mountain, you can also share today's TV series, movies, and MTV with your lover.
2. Business trip: Portable projectors are easy to carry because of their small size and light weight. When you need to display computer content or mobile phone content, you only need to connect the portable projector to achieve the demonstration effect.
3. Private space: For dormitory beds or small private spaces, in the absence of a computer, you can use a portable projector to project the content of your mobile phone to watch video pictures, etc., without staring at the mobile phone at close range.
