| Abstract: | With Slow start, low efficiency, operating current small against traditional power driver circuit, and power supply technology of the optical fiber laser going into the development trend of high integration, high response, a new design of synchronous Buck circuit based on the control of TPS40055 is presented in this paper. It can achieve respectively 3-way DC power output of PWM and adjustable current for high power fiber laser. voltages are 3.3 V, 5 V, 10 V , currents are 0 ~ 11A adjustable. The new power circuit design from these espects of general planning, working principle, parameter design, and optimization is introduced in this paper.The results show that a high efficient, reliable, stable power DC-DC for fiber laser can be provided from the design. |
