Ir2153 Smps With Short Circuit Protection. This smps was up and running but i have little problem when im feed it with high load. The 300w version gives 2x44v dc.
Smps details 2 x irf740 ir2153 run freq is 100khz protection use current sense trafo 4x 1n4148 mcr100 output voltage 43 5 and 43 4 output diode mur420 x4 output. According to the ir2153 integration the greatest feature of the ir2161 is the built in current sense short circuit protection system the power mosfet is protected against the current drawn through the low ohmic shunt resistor connected to the source pace unfortunately the working frequency can not be adjusted with external components this has a working frequency of 70khz. Mosfets may be stressed on power up because they have to charge the output capacitors.
Mosfets may be stressed on power up because they have to charge the output capacitors.
The switching power supply is utilizing two n mosfets driven by integrated circuit ir2153. Ir2153 smps with short circuit protection. Smps designs designed as ir2153 amplifier power source based on ir2153 integration. In general ir2153 supply voltage is taken over 220v filter capacitor that is over 310v resistor or mosfet regulator.
