Abstract
A signal transmission deviceincludes an isolated signal transmission circuitconfigured to transmit a pulse signal from a primary circuit systemvia a first isolating element ISOto a secondary circuit system, and an isolated power supply control circuitwhich serves as a controlling agent of an isolation-type power supply that generates a second supply voltage Vccfor the secondary circuit systemfrom a first supply voltage Vccfor the primary circuit systemand which transmits an output feedback signal of the isolation-type power supply from the secondary circuit systemvia a second isolating element ISOto the primary circuit system
