The output of this power supply is an isolated 3.3V/10A output, produced from an input is 36-72V DC. Airflow is required at higher ambient temperatures to get the full rated power. The topology used is a single transistor forward, with a reset winding on the transformer to reset the core. The maximum duty cycle is [...]
This is the DC switching regultor Voltage 5V at current 3A. It is make for digital circuit. The important part of the circuit is LM2673, it is 3A Step-Down Voltage Regulator with Adjustable Current Limit. The LM2673 is Simple and easy to design with using off-the-shelf external components. please see circuit diagram and read more [...]
When i want 5V switching regulator (mini project),so i am used input is 9V battery. The good circuit for work is the IC LT1073-5 (see detail in www.linear.com), it out put 100mA current. The zener diode is 1N5818,L1 = 100uH Detail more please see in image. Related Links All circuits of Switching power supply All [...]
