Part Number: UC3526 Hi,
We used uc3526 PWM controller IC for full bridge converter topology with 100kHz frequency for 1.2kW. But the input side of transformer, we are not getting proper pulsed dc waveform. Ringing is more and we cant see the dead time…
Part Number: UCC28950 Other Parts Discussed in Thread: UC3526 , UCC29002 Currently, I have designed a DC-DC isolated converter using UC3526 and push-pull topology, which provides 36-60VDC input and 96VDC output. These designs have turned into 900W modules…
Other Parts Discussed in Thread: UC3526 Hi!
Currently I am using UC3526 for 40KHz PWM generation.
During testing, i had observed after power up for few seconds i am getting the output A & B but then it vanishes.
As per datasheet, I am geeting SYNC…
Rashmi,
Make certain that you have at least a 1 uF cap from Vin to GND and that Vin and Vc arre connected. You need a resistor to Rd as well as the ones you have added. connect a 0.1 ceramic from Vref to GND.
Apply a 15 volt supply between Vin and GND…
