Shenzhen Jiao Technology Co., Ltd. China (Mainland)

Shenzhen Jiao Technology Co., Ltd. is a worldwide and leading manufacturer of standard, modified standard and customized switching power supply AC/DC adapter and linear switching power supply from 1/2watts to 80watts. We are an ISO9000 certified company and are headquartered in Taiwan. Our company is dedicated to the advanced research and development, supported by sophisticated manufacturing automation and in-process testing to deliver low cost and high quality power supply solutions to clients. A switched-mode power supply, switching -mode power supply or SMPS, is an electronic power supply unit (PSU) that incorporates a switching regulator. While a linear regulator maintains the desired output voltage by dissipating excess power in a "pass" power transistor, the SMPS rapidly switches a power transistor between saturation (full on) and cutoff (completely off) with a variable duty cycle whose average is the desired output voltage. The resulting rectangular waveform is low-pass filtered with an inductor and capacitor. The main advantages of this method is greater efficiency, because the switching transistor dissipates litter power in the saturated state compared to the semi conducting state and the off state compared to the semi conducting state (active region). Other advantages include smaller size and lighter weight
