Part Number: UCC28C45-Q1
Hello,
The above diode helps in discharging the soft start capcitor under UVLO condition to gain back soft start feature.
As I simulate its behaiour, the peak current through diode is 2A which ramps down to 0 in 20-30us…
Part Number: UCC28C45 Tool/software: Hi，
The DCDC module uses UCC28C45 with an output voltage of 12V. If the voltage exceeds 12V, the driver will shut down. There is no problem using the old chip and it works normally. The chip recently purchased by…

Part Number: UCC28C45 Tool/software: Hi,
My customer now is wondering the difference between the A1 version and A version. Is it from different wafer vendors as RFAB is authorized since PCN released? Could you please help explain it? Thanks.
Thanks…
Part Number: UCC28C45 Tool/software: For PN UCC28C45DGKR we have 2 markings available.
28C45 and 2C45
What is the difference between the 2 markings? What does "8" in 28C45 mean?
