Id OUTPUT Vin Vin SUPPLY VOLTAGE FOR CONTROL CIRCUIT T 60 01 3 OTHER FUNCTION unction Built in Overvoltage Protection Circuit Built in Thermal Shutdown Circuit 4 EXPLANATION CIRCUIT OPERATION 1 ViN terminal start up circuit A Start up circuit is to start and stop a operation of a control IC by detecting a voltage appearing at a VIN terminal pin 9 At start up of a power supply when a voltage at the VIN terminal reaches to 8V by charging up C809 by the function of a start up resistor Rs a control circuit starts operating by the function of the start up circuit As shown in Fig 2 since a circuit current is suppressed 200 maximum at VIN 7 5V until the control circuit starts its operation After the control circuit starts its operation power source is obtained by smoothing voltage appearing at L1 winding Once the control circuit starts operating as its voltage doesn t reach the fixed voltage at once VIN terminal voltage starts dropping However as a shut down voltage is set low at 4 9V while terminal voltage reaches a shutdown voltage L1 winding voltage reaches the fixed voltage earlier so that the control circuit can continue on operating INN Fig 1 Start up Circuit Fig 2 Vin Terminal Voltage Circuit Current 2 Oscillator F B terminal voltage Pin 7 A oscillator generates pulse signals which turns a power transisto
