3 Description of HSTR28S Series Transient Suppression DC/ DC Converters
This series device is highly reliable and is featured with surge protection (80v, 1s) for DC/DC converter. Single ended, pulse width modulated and transformer magnetic feedback topology design is 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.
Devices are produced by using thick film hybrid integration process, and metal package sealing. The design and manufacturing process of HTR 28 Series ofbest dc dc converteris in compliance with General Standards of Hybrid Integrated Circuits and detailed specification of manufacturing. Input terminal connected to the accessory power supply filter can improve the electro-magnetic compatibility of devices.
