GS1T70-D540F 数据手册
GS1T70-D540F ISDN DC-DC CONVERTER (FRENCH VERSION) Type GS1T70-D540F Vi 25 to 115 V Vo 5V 40 V Io 90 mA 10,5 mA FEATURES Wide operating line termination battery voltage Peak input overvoltage withstand: 1kV for 1.2/50µs Peak overvoltage withstand on Output 2 (40V): 250V for 10/700µs Positive or negative input voltage polarity Input and output filtering Short-circuit protection on both outputs Input power during shortcircuit within specification Minimum current drain during stand-by condition: 10µA for Vi 25V, the circuit operates correctly, because it lies in the Voltage Supply Operating Area. The converter goes in High Input Impedance mode (Iq < 10µA) when the Vi is lower than 10V. If Vi remains between 0 -10V range for almost for almost 100 ms, the converter is in OFF condition. - Switch OFF-ON sequence: The quiescent current Iq remains below 10µA if Vi is lower than 18V. The start-up voltage is between 34 to 44V. After 1 ms in this condition, the converter is in Voltage Supply Operating Area (Vin = 25 to 115V). Figure 2. Vi 115V Voltage Supply Operating Area 44V 34V Voltage Supply Operating Area 25V 18V 10V Iq < 10 µA Area 0V Iq < 10 µA Area t t>1mS t>100mS Information furnished is believed to be accurate and reliable.
