The application of dcdc power modules in switching power supplies is nothing more than step-up or step-down. However, due to the improvement of science and technology, more isolated and unregulated micro-power dcdc power switch modules are currently used. If only from the role of isolation, It is recommended to choose B0505S-1WR3 (dcdc power module) of Huizhi Electronics for the model of switch application.
The output voltage of the isolated dcdc power module B0505S-1WR3 is only 5v, and the output voltage is between 4.5 and 5.5v, forming a 5v to 5v unidirectional output mode, which has the function of isolating and protecting the switching power supply, and also improving the conversion efficiency of the switching power supply. The specific feature of this dcdc power module is a small size, high-efficiency micro-power power module. At the same time, due to the constant voltage, the input is isolated and unregulated, the single output mode can automatically recover in the case of a short circuit of the switching power supply, and relay protection power supply.
Isolated unregulated single output dcdc power module B0505S-1WR3 package is single in-line, fully enclosed plastic shell, mainly black flame-retardant and heat-resistant plastic, conforms to UL94V-0 level, this product has low energy consumption and low charge , One-way transmission of power is fast. Due to the excellent production technology of Huizhi Electronics, the B0505S-1WR3 with a small power of 1~3w can replace the power supply module with the same parameter input and output voltage and power range and be applied to the power switch.
