Part Number: UCC28950
Hi,
We are evaluating a PSFB converter using the UCC28950 and have observed oscillation in the transformer current and output inductor current under a specific operating condition.
The issue occurs only when the timing difference…
Part Number: UCC28950 Hello,
I am designing a PSFB charger with UCC28950. Charging method will ve CC/CV and I designed error amplifier of CV mode and selected compensate components in according to calculator excel that is shared in TI product page.…
Part Number: UCC28950-Q1 Other Parts Discussed in Thread: UCC28951 , UCC28950 Hi,
Does TI make the UCC28950 or UCC28951 in a military grade version that operates down to -55°C and up to 150°C? There is nothing listed in the datasheet, but I was curious…
Part Number: UCC28950 Dear TI Engineers,
I'd like to enquire regarding an issue I am currently facing in simulation. I am using the UCC28950 and its pspice simulation file (slum169c) and its associated EXCEL calculation tool (SLUC222). However, despite…
Part Number: UCC28950 Dear TI Team,
Please review the schematic. of the power supply
Input: 3-phase or single-phase
output : 12/3A, 5V/3A, 24V/3A
We want to use phase-shift topology If you have any better recommendations or part selections, please…
Part Number: UCC28950-Q1 Other Parts Discussed in Thread: UCC28950 , UCC28070 HI TI team
During standard power-on with either a light load or full load, the output voltage exhibits no overshoot. Conversely, if the OVP trips, the AC power is subsequently…
Part Number: UCC28950 Other Parts Discussed in Thread: UCC28070 , Hi,
Q1) We believe that frequency synchronization would be possible between PFC converters or between PSFB converters. However, is it possible to synchronize the switching frequencies…
Part Number: UCC28950 Hi Anil,
Thanks for revert.
We need two models for variable (programable) power supply (Model 1 & Model 2) as below specifications. Please suggest suitable flyback PWM controller for this application
For Model 1 Vout : 3V-63V…
