Part Number: TIDA-00443 Tool/software: Hi sir, I have checked with the Controller gate signal generation to the gate driver the controller is generating the signal but while increasing the voltage gradually the duty cycle is not reducing it stays at 95…
Part Number: TIDA-00443 Tool/software: Hi sir,
My name is Vishaal and i am currently an B.Tech. Undergraduate. we have implemented the hardware model of TIDA-00443 and currently in testing part. we have an issue while testing the hardware where after…
Part Number: UCC28180 Other Parts Discussed in Thread: TIDA-00443
Tool/software:
We have designed a power supply referring to TI's reference design: TIDA-00443. The main differences are that we replaced D2 in the design with 1N5408, D1 with STBR6012W…
Part Number: TIDA-00443 Hi,
In section 4.2.4, the VF_bridge per element is taken as 0.85 V for loss calculation. Could you please let me know from where this information is obtained. In the datasheet of GBJ1508, it is only mentioned that VF_bridge per…
Part Number: TIDA-00443 Other Parts Discussed in Thread: TIDA-01503 , Can I use TIDA-01503 board bias power to the TIDA-00443 ?
Is there any other better suggestion?
Part Number: TIDA-00443 Hi,
In section 4.2.8, how the second part of the power loss (0.5*fsw*Vout*Qrr) is derived.
I understand it is due to Qrr, how exactly is the equation derived. Could you please explain.
Thanks and regards,
Part Number: TIDA-00443 In section 4.2.6, the switching frequency used is 98 kHz instead of 100 kHz. What’s the reason for this.
If we look at the schematic, it is found that two 0.68 uF caps are used. Could you please let me know why two caps are used…
Part Number: TIDA-00443
Referring to section 4.2.6in the design document, I can find that the Iripple = 2.75A.
I calculated the RMS current as shown below:
The data sheet of the selected capacitor shows that at 100kHz, it can carry an RMS current…
Part Number: TIDA-00443 Dear TI Experts,
I was referring TIDA-00443 Reference design from TI. TI used three 220uF capacitor C4,C5 and C18 at the output of PFC. What is the total power dissipation in these capacitor?.
TI calculated the ripple current…
