Part Number: UC3845 Hello,
I am using UC3845 PWM IC for flyback topology for 24v5 amps Output .Here I noticed while continuous current of 4amps @24V IC getting heat, around 80 degree centigrade.
Input Voltage :40VDC
Output Voltage 24V @ 5AMPS…
Part Number: UC3845 Hello,
We are currently using one of your DC-DC converter ICs (UC3845) for a 5V/21Watt power supply.
This power supply is primarily employed in a telecommunication system where noise is a significant issue throughout operation…
Part Number: UC3845 Tool/software: Dear TI Expert,
We are designing dc -dc buck converter using UC3845.
Please help to design inductor for the following parameters.
1. Input Voltage Range - 30 to 72 Vdc.
2. NO load Output Voltage - 13.80Vdc…
Part Number: UC3845 Tool/software: Hi expert,
Pls see below schematic. After place C30 in VREF pin, Vref output voltage will be probabilistic anomalies. After delete C30, Vref output fault voltage cannot be reproduced.
The first waveform is normal…
Part Number: UC3845 Hello,
I have designed a flyback circuit and I have used UC3845 for the following configuration input 12-18 V. Output 48 V 1 A. I attached the Altium schematic pdf file below.
However, I could not get any gate signal from to UC3845…
