Part Number: UCC28C44 Other Parts Discussed in Thread: TL2844 Hi team,
My customer want to do early evaluation on thermal test by just pin 2 pin replace TL2844 by UCC28C44 since UCC28C44 has lower start up and working current than TL2844. Should we advise…
Part Number:
1. What is the role of Qsc? Can it be removed?
2. Can WE replace Q1, DZ and RZ with resistors?
3. For the resistance and capacity of the generated reference design, we will select similar values from the existing material library.…
Part Number: TL2844 Dear Teams,
My customer is using TL2844 for their AC/DC power supply, and they found the temperature rise is more than 40 degree. VCC supply voltage for TL2844 is 14-15V. Could you help review the schematic diagram for customer and…

Part Number: TL2844 Figure 16 in the DS has Note A) which defines an equation for calculating the oscillator frequency.
Using 3.6kΩ and 1nF, the expected frequency was around 480kHz.
Figure 10 in the DS seems to confirm this.
But the actual measured…
Part Number: TL2844 Other Parts Discussed in Thread: UC2844 , Hi Experts,
May I know what's the difference between UC2844 and TL2844? It looks like the specs are almost the same, which one is preferred?

Part Number: TL2844 Hi,
I attached our schematic for HMI-SMPS application as below.
I used TI's PWM controller TL2844 and FAIRCHILD's FET FCDB1300N80Z.
At the sample board, PWM cont. and FET damaged repetitively when test.
So I'd like to get TI's…
