I am in design mode, still trying to select a good DC/DC chip for my purposes. I don't have a working PC board yet, and output ripple isn't the concern.
My application requires using an unregulated power supply. The supply voltage will be 12 V typically…

Hi,
Is the brownout occurred at low dropout and light load on the TPS54202.
Brownout → www.ti.com/.../slva547a.pdf
On other words, is the Boot cap charged by turning on…
Part Number: TPS54202 Hello,
I am using the TPS54202 with VIN = 5V, VOUT = 3.3V, IOUT = 0.6A. I should be always enabled: so I left the EN pin floating, but it is OFF (0V on output) both with load (6 Ohm = 0.6A) and without load.
I tested two boards…
Part Number: TPS54202 Hi team,
My customer is asking us what could happen if SW node is biased to 5V externally when Vin is open or short to GND. I believe no device damage happens since it is within the maximum rating. What could happen on VIN, BOOT…
Hi Mike,
I am using TPS54202 which i have followed the data sheet design and layout exactly. The input is a nice and clean 24V with no transient and ringing. The load is less than 100mA, which this part should have no issue handling, but so far three…
Part Number: TPS54202 Other Parts Discussed in Thread: TPS561208 , Hi all Would you mind if we ask TPS54202? <Question1> We have questions of the test condtion of Figure 27 to Figure30. How much is the current condition(Iout) about Figure 27 to Figure30…
Part Number: TPS54202 Hi,
We got a question from customer about TPS54202. Could you help us?
[Question] How much is the output voltage of internal regulator? They want to estimate charging voltage of boot capacitor.
Best Regards, tateo
Chris,
At that time, we are thinking about the loop stability issue because of the internal compensation. And then, we did many experiments and found it was OK. But the output current can not be up to 2A. And, as your input is 24V and output voltage…
Other Parts Discussed in Thread: TPS54202 Dear Sir,
I learned TPS54202 needs 5pcs *47uF output capacitor for vout 1.x V application.
Can I decrease capacitor amount by adjusting C6 capacitor? Thanks.
