Part Number: LM5069QUICK-CALC Other Parts Discussed in Thread: LM5069 Dear team,
I'm using the LM5069 Design Calculator with FET Recommendation for SOA calculation
However Some of the green cells in the calculator is invalid.
1. can't set the load…
Part Number: TPS552882 While performing WCCA, I've noticed that the calculated inductor(9.6uH-> Even at nominal values) is far less than the recommended value from both webench & excel calculator(max.2.5uH). Added the webench report here for…
125W PSR Flyback--LM5185-DESIGN-CALC.xlsx
Hi Youhao,
Herewith attached the 125W_PSR_Flyback_LM5185_Calculation for your review, I need your help on flyback transformer calculation part and efficiency curve verification. Expected efficiency 85-92%. Please…
Part Number: LM5022
Hi TI experts,
For LM5022 based flyback design, we measured there is about 20ms delay from Input ramps up to Vout starts ramping.
Can i know why there is a delay?
How can we reduce the delay?
Thanks.
Input and output waveform:
Green…
Part Number: TPS23734EVM-094 Other Parts Discussed in Thread: TPS23734 , TPS23731 , TPS23731EVM-095 , PMP22806 Hello,
TPS23734EVM-094 have been designed for evaluating the TPS23734 in a forward SMPS topology.
There is an existing (or in design) evaluation…
Part Number: UCC28711 Tool/software: Hello! I'm curious about what elements need to be changed and if there are any reference materials available if you want to increase the capacity to 100W in the topology of a 400- to 690-V AC Input 50-W Flyback Isolated…
Hi Neo,
I would not cut the trace on the PCB but either rotate or lift up CR12 so that it das not contact on the anode side and then blue wire.
I would like to checkout if the diode (e.g. with its reverse recovery charge) and the Softstart caps C1105…
Part Number: UCC3803 Tool/software: Hi,
I want to design a custom SMPS with the required specifications:
Input voltage min: 22V; Input voltage max: 26V (Nominal input: 24V)
Output voltage: Isolated +150V-0-(-150V)
Output power maximum: 25W
Output voltage…
Hello team,
In my application, I need to design an insulated 24Vdc input to a 5Vdc 1A output voltage source with a minimal insulation of 5kV between primary and secondary. I believe the Flyback topology with a UCx84x controller would be suitable. However…
Part Number: FLYBUCK-DESIGNER Other Parts Discussed in Thread: LMR38020 I am learning flybuck and i have some questions about it:
1. Why its secondary voltage regulation doesn't perform well when the primary is no-load and the secondary is loaded, espe…
