摘要： A wide input voltage power supply circuit for a load includes a first regulation stage and a second regulation stage. The first regulation stage includes a linear regulator circuit configured to maintain a bus voltage within a predefined voltage range when an input voltage exceeds a predefined input level. A second regulation stage includes a buck converter circuit configured to regulate an average bus voltage to a predetermined load level. The second regulation stage includes an under voltage lockout configuration, with the under voltage lockout configured to set a minimum turn-on voltage for the load.

摘要： An under voltage lockout circuit configured to set a minimum turn-on voltage for a load is provided. The circuit includes an input terminal configured to receive an input voltage. The circuit includes a first transistor configured to become conductive to supply the input voltage to the load when an input voltage to the under voltage lockout circuit exceeds a threshold, and a second transistor coupled to the first transistor, the second transistor configured to become conductive to supply the input voltage to a first resistor and not to the load when an input voltage to the under voltage lockout circuit falls below the threshold.
摘要翻译：提供了一种配置为设置负载的最小导通电压的欠压锁定电路。电路包括被配置为接收输入电压的输入端子。所述电路包括：第一晶体管，被配置为导通，以在所述欠压锁定电路的输入电压超过阈值时向所述负载提供输入电压;以及第二晶体管，耦合到所述第一晶体管，所述第二晶体管被配置为导通当输入到欠压锁定电路的电压低于阈值时，将输入电压提供给第一电阻器，而不是负载。
