Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Other Parts Discussed in Thread: TPS53313 E2e,
We have a customer with four TPS53313 regulators in their design. The customer wants each regulator to switch on a different phase of a clock. Does TI have a solution to generate this clock? If so, what do you…
Other Parts Discussed in Thread: TPS53313 Hello I have some TPS53313 and do not work corretly,we find that PIN 20, 21 and PIN 22 are short circuited internally, and I don't Know if i'm doing something wrong. I used like reference design the Data Concentrator…
Other Parts Discussed in Thread: TPS53313 The data sheet (pg 12) states:
The clock frequency is programmed by the value of the resistor connected from the RT/SYNC pin to GND. The
switching frequency is programmable between 250 kHz and 1.5 MHz.
Also, TPS53313…
Other Parts Discussed in Thread: TPS53313EVM-078 , TPS53313 In the Diagram ,the source of high-side FET connect to BP7 seems error. Is the source connect to Vin.
I make a similar board to EVB, the out put is set to 1.8V. It do not not work when Vin below…
Other Parts Discussed in Thread: TPS53313 using these parameters:
vinmin=10v
vinmax=13.2v
vout=6v
iout=1.25a
run webbench
select tps53313
get rfb1=2k
rfb2=18k
Databook calculations show r2=.6/(vout-.6)*r1 so r2 should always be less than r1. Databook…
Marion,
Those components are for an external ripple injection circuit. TPS53313 uses DCAP3 control mode. Thee is an internal ramp generator, so in most cases the external ripple injection is not required.
Hi Martin, thanks for your reply.
I found that the SW rating of TPS53313 can down to -2V (DC). does it mean TPS53313 is more reliable than TPS54622 (-1V DC on PH)? any special in the TPS53313 for the SW pin? I mean why it can down to -2V?
Hi Biser,
Thanks a lot for your kind information.
But the max input for the TPS53313 is 16V and there's a fuse protect the power circuit. I think the DC is still OK because the TPS53313 could output 5V normally.
The SW2-Reset switch lost the reset…
