Which valley the FET turns on changing during a "steady state" operation can be expected operation.
UCC28700-Q1 has frequency jitter to reduce EMI, which modulates the switching frequency slightly at a steady state operating point. …
Part Number: UCC28700-Q1 Dear TI Team,
I am designing the UCC28700-Q1 and have a problem during the test to request help.
1. The waveform of VDD is measured as shown below.
It seems to swing from 21V to 7V with protection.
Debugging contents are as…
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700 , TINA-TI , when I use TINA to load PSPICE model of UCC28700, the symbol also didnt work too.seek for help, thank you very much
Part Number: UCC28730-Q1 Dear TI Team,
I am designing with UCC28730-Q1. I would like to design with the following specifications, but I need a guide for transformers. The specifications we will design are as follows. ▣ SPEC: - Input: 85 ~ 265Vac / 60Hz - Output…
Part Number: UCC28700-Q1 Hello,
I am using UCC28700-Q1 for DC-DC converter. In the typical application circuit of the datasheet (Page No. 17) Primary & Auxiliary side of transformer are out of phase (as per dot conventions) but in attached design ( even…
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700 , I want to simulate Power supply using UCC28700 in LTSPICE, but the UCC28700 was encrypted, so I need to build similar function model as UCC28700.
I tried to use auxillary winding signal…
Part Number: UCC28700-Q1 I am using UCC28700-Q1 for DC-DC converter. The designed circuit is same as per the typical application circuit mentioned in datasheet of IC (Page No.17) which is modified for DC to DC converter with Vdd= 12 V .
But while testing…
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hello,
I've downloaded the UCC28700-Q1 model from your website. If I import the (encrypted) netlist in TINA-Ti and compile it I get the following…
