Switching power supply of 15-volt 220 mA with the cooperation of Mr. Massoud Hassanzadeh
It was designed to be a project that, according to the order of a company, we must take part in
The space was very small (about 3 in 5 centimeters), which was designed to be fortunate enough
We were able to design this board in this very small space because of this space
We had very little use of very small pieces that could be in this much range
We used this low board for this circuit. We used the kernel (EE16 six pins) that’s fine
It was able to handle this much-needed amount of power
Optimal design of PCB2 –
Special design of trans-switching with minimum leakage inductance and Parasitic capacitors
۳٫ Use of ICs with related protections 4
. Use of low-VF shaft diode- Use of high quality and original components
۶٫ Use of SMD components to reduce space Width
۷ – Dimensions of the feed board 35 mm in 55 mm
The technical characteristics of the switching power supply is 15 V 220 mA.
– The voltage range of the input voltage is 88 V to 265 V AC
۲٫ The output voltage is 15 V DC and the output voltage can be adjusted and adjusted according
to the customer’s order.
۳٫ Output current of 250 mA and 500 mA 4
. – Width 35 in 55 mm with a height of about 3 cm.
۵- Circuit efficiency of at least 75% and maximum 85% in full load.
۶- Power factor of 55%.
۷- Top-flange. 8- Output stability with accuracy of 100 mV at maximum.
۹٫ Working ability at temperature. 50 ° C 10 – Probe circuit for short output
From the applications of this switching power supply,
I can refer to the following: 1
. Suitable for driving the MOSFET and IGBT
۲ gateways – Suitable for microcontroller and electronic circuits.
۳٫ You can see the switch for a mobile charger below the images of this circuit.
