Part Number: UCC24636 Hi team,
My customer is using our UCC24636, and they find our device have a 540ns turn on delay time.
Please kindly help check if this 540ns is correct? What is the normal range for turn on delay time and how can customer qreduce…
Part Number: UCC24636 I recently used webench to create an "mains" ac to 5v dc isolated converter (see https://webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=829567FEA10E90C3 )
i noticed that the output has a resister Rpl between 5v+ and GND while…
Part Number: UCC24636 We are trying to design a power generator circuit using the UCC24636 IC. The encrypted spice models available online are giving simulation error of "too few nodes" in LTSpice. Can anyone provide the unencrypted spice model file for…
Part Number: UCC24636 Dear Expert
My customer start up synchronous rectifier burning MOS DS Pin . This kind of failure phenomenon has about 4 sets, a total batch 500 sets.
Below is schemeitc :
Could you give any suggestion how we locate where…
Part Number: UCC24636 Hi Sir：
I use the ucc24636 as auxiliary power controller, Vout =12V.. And I use the excel UCC24636-Calc to set the external resistance. I have a resistor Q1 in parallel and Q1 is 1200V MOSFET. it Out of work,The Vout i can get…
Part Number: UCC24636 Our customer found folloing SR timing delay waveform. (delay time: about 550ns)
<Condition>
IN:DC240V-DC340V
OUT:13.5V/4A
Also they didn't found low Vin and light load condition.

Our customer consider to use UCC24636 with Low-Side SR Configuration.
Please see attched waveform. 2541.waveform.xlsx
1.Is this waveform normal .?
2.Can they extend DRV ON time ? Please let us know how to extend DRV ON time…
Part Number: UCC24636 Our customer consider to use UCC24636 with High-side SR configuration with Bias winding.
Please check attached fole and advise about RVPC,RVSC.

Hello Jim,
Thank you for your interest in the UCC24636 SR controller (and UCC28740 flyback controller).
You are correct; the UCC24636 cannot be directly powered from a 120V source. Nor can the 100-V MOSFET, and also not the shunt regulator. I…
Part Number: UCC24636 Other Parts Discussed in Thread: UCC24624 Dear Team,
our customer uses the UCC24636 for an industrial battery charger. The first version had an output voltage of 11-15.6V, so no problem.
In another project they are looking for…
