Abstract: T flip flop IC a PWM IC, Unitrode part #UC3844. An auxiliary winding on the transformer is used to generate a VCC , LR7 GND VOUT VCC PWM IC UC3844 C1 Figure 1: Simplified SMPS using LR7 3 LR745 , where, In Figure 3, the VREF pin of the UC3844 is used to bias the ground pin of the LR7. The VREF pin on the UC3844 is a 5.0V reference, which stays at 0V until the VCC voltage reaches the start , UC3844 will start to operate and VREF will increase from 0V to 5.0V. The LR7 will see an effective VOUT
