Part Number: UCD74120 Other Parts Discussed in Thread: TCI6636K2H , , TMS320C6678 , UCD9244-EP , UCD9244 Hi,
I am using TMS320C6678 processor. The variable core voltage CVDD is consuming around 15A. Since UCD7242 has a 10A limitation, we have used UCD74120 as shown…
Part Number: UCD74120 Other Parts Discussed in Thread: LMZ31710
Hi,
In the datasheet of UCD74120, it is recommended to connect analog ground (AGND) and power ground (PGND) at one point near AGND pin. These are my doubts:
(1) Is AGND pin connected to…
Part Number: UCD74120 Other Parts Discussed in Thread: TMS320C6678 , UCD9244-EP , , TPS40422 , TPS40428 , TPS40322 , UCD9222 , UCD7242 Hi TI team,
In our design, we have two TMS320C6678 DSPs (D0 and D1). The variable core voltage (CVDDD) for each the DSPs consumes…
Part Number: UCD74120 Other Parts Discussed in Thread: UCD9244 ,
Hi,
I am using UCD74120 with UCD9244 (smart reflex interface) to power the variable core voltage (CVDD) of TMS3206678 multicore DSP. The CVDD rail draws around 15A current.
I am trying to…
Part Number: UCD74120 I am using UCD74120 to generate CVDD (1V) voltage for K2K SoC. On checking the voltage across the capacitor of value 220nF (as recommended in the datasheet) connected to BOOT pin of the same IC, it is expected that the output voltage…
Part Number: UCD74120 Elsewhere in this forum there is a thread with an efficiency graph of the UCD74120 operating at 500 kHz with an inductor ESR of 1.2 mOhm.
We need similar data for:
Vin = 12V, Vout = 0.9V, inductor ESR = 3 mOhm,typ (Coilcraft XEL5030…
John,
I'm sorry I never got back to you on this. Do you still need assistance here? What frequency is the power stage operating at (I'm sorry if I missed that).
Part Number: UCD74120 Other Parts Discussed in Thread: UCD9244 , UCD74120 design driven by UCD9244. UCD9244 says the current on the output is about 3.8 amps no matter what the actual load is. Design was done with Fusion Digital Power Designer 1.9.78

Part Number: UCD9244 Other Parts Discussed in Thread: UCD74120 UCD9244+ UCD74120 K2H EVM Query
I wanted to understand the Configuration for these ICs using Fusion Digital software.
What all inputs I need to prepare and how it works?
Also It is powering…
Part Number: UCD9224 Other Parts Discussed in Thread: UCD74120 , , UCD9244
We have assembled our board and facing issues in powering up the SOC (K2K). We are consistently seeing SOC power failure in the LCD of Microcontroller.We have made sure all the…
