| DD1B150 | Thick film hybrid techniques provide the DD1B150 Series converterswith high reliability and optimum miniaturization. The design andmanufacturing process of DD1B150 Series converters complywith MIL-PRF-38534. The DD1B150 series products are high reliable surge protection DC-DC converters featured with transient protection (80 V, 1 s).In these products are used single ended fly-back, pulse-widthmodulated and transformer magnetic feedback topology design.The operating principle is that the sampling signal of outputvoltage, coupled by the transformer, works together with thesampling signal of input loop current to regulate the pulse widthof the controller. | Protected DC-DC module 1.5W | High-reliability electronic system for aviation, aerospace and some applications of high input transient suppression requirements. | Download |
| DD1A201 | Thick film hybrid techniques provide the DD1A201 Series of converters with high reliability and optimum miniaturization. The DD1A201 series device is high reliable and is featured with surge protection. Single ended flyback, pulse-width modulated and transformer magnetic feedback topology design are used in this device. The operating principle is that the sampling signal of output voltage, coupled by the opto-coupler, works together with the sampling signal of input loop current to regulate the pulse width of the controller. The double loop control creates constant voltage output and short circuit protection. | Protected DC-DC module 20W with single and dual outputs. | High-reliability electronic system for aviation and aerospace. | Download |
