Part Number: TMS320F28335 Other Parts Discussed in Thread: TPS3307 , TPS62040 I would like to ask a question. After power-on, 28335 program does not work, at the moment, the power supply, crystal oscillator and power supply ripple are normal. then, pull…
Other Parts Discussed in Thread: SWITCHERPRO , TPS62040 Is a SPICE model for the TPS62040 planned? I cannot find it in Spicerack or SwitcherPRO. Please advise when you can - thank you.
Other Parts Discussed in Thread: TPS62040 The TPS62040 output voltage appears to be unstable. The switch node is very noise and there is a lot of jitter. The duty cycle is not constant and changes from a value that is too low to a value that is too high…
Other Parts Discussed in Thread: TPS62046 A customer has done board testing in temp oven with 1.5uH inductor and seen the failures.
At that time, they used a long input power cable that caused input voltage spike to go over 7V ( abs max of the part is…
Mr Coxe, A few questions: 1) Is the MCU or the dual-switcher (TPS62040) getting hot? This may lead to thoughts about a short or a layout problem respectively. 2) Can you try changing out what would be L11-L18 in your schematic and make them 0R0 resistors…
