Hi Jason,
I have results from using the LM5166 EVM.
The EVM was modified to use the component values in the image below. The component values were chosen using the LM5166 quick start calculator.
The EVM was connected to 5V and GND test pads on my design…
Part Number: LM5166 Hello team,
I'm looking for a buck DCDC solution which can use with variable output use case and LM5166 would look to be a device. Let me ask a couple of questions below. 1) Is the LM5166 able to be used with variable output on the…
Part Number: LM5166 Other Parts Discussed in Thread: ALLIGATOR , , My original thread was closed ( https://e2e.ti.com/support/power-management/f/196/t/914047 ) so this is a follow up to that thread where we discussed different layout options. I was able to…
Part Number: LM5166 Is there a minimum size for the feedback resistors? Datasheet section 7.3.4 recommends the range of 100KΩ to 1MΩ and warns against larger values, but does not mention smaller values. I ask because I need to handle some reverse…
Hi David,
LM5166 has design example of input 4.5V--36V to output 3.3V 0.3A conversion, the inductor is designed for Fsw = 600KHz at 24V nominal input, so the Fsw will be 631KHz at 36V input based on same inductor. actual switching freq can be slightly…
Part Number: LM5166 Other Parts Discussed in Thread: TPS561201 I am having a similiar issue where the converter shuts down during operation and requires a power ccycle to restart.
It is configured as 48V to 12V stepdown (PFM mode) and supplying about 0…
Part Number: LM5166 Other Parts Discussed in Thread: LM5007 Tool/software: WEBENCH® Design Tools Team,
My customer is looking for an inverting buck-boost: 36V input, -8V output @ 0.3A. I am looking at the LM5166. Is this possible? How do I have to configurate…
Part Number: LM5166 Other Parts Discussed in Thread: LMR36006 I am considering using the LM5166 in a design where it will sometimes act like an on/off switch for LEDs. The LED forward voltage is about 9V, so my idea is to set the LM5166 Vout to 12V and…
Part Number: LM5166 Tool/software: WEBENCH® Design Tools Vin = 36 V und Vout = 7.8 V; Maximum load current at 7.8 A = 0.3 A, Fsw = 300 kHz
Is this a correct design of my circuit for the parameters? Is it possible to combine tantalum capacitors and ceramic…
Part Number: LM5166 Hi,
As I understand it, there are discrete current limit thresholds on the LM5166. The datasheet gives specific resistor values to connect to the ILIM pin to select one of them. What is the tolerance on those resistor values? If I…
