DC DC Power Chip

Independent design, professional production, DC-DC buck IC. Synchronized rectification technology is adopted with high efficiency and lower temperature. Frequency is 120-500K, adjustable, and easy to pass EMC UL KT and other international security certification. According to the demand, the current limiting point can be set accurately or the fuzzy current limiting can be used flexibly and conveniently. The supply current of our company is 1 ~ 10A, and the input voltage is 30 ~ 100V. It has strong selectivity.
