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.
Part Number: TPS56C215 Other Parts Discussed in Thread: TPS56C231 , , TPS56C230 Tool/software: We were using IR3475MTRPBF in one of our projects. Now that IC got obsolete and we have searched out TPS56C215RNNR for that application.
My question is what…
Part Number: TPS56C215 Tool/software: Dear E2E Forum,
I'd like to place a decoupling capacitor at the mode pin of TPS56C215. How much capacitance can this pin tolerate?
There's 200kR from VREG5 to MODE and 10kR from MODE to PGND, so according to…
Part Number: TPS56C215 Hi,
I have a question about TPS56C215.
I was wondering if i could use same GND plane with AGND and PGND.
In datasheet, there is a single point AGND to PGND connection.
Is it okay to tie both GND plane without any distinction between…
Part Number: TPS56C215 Hi,
I tested TPS56C215 static load ripple and efficiency under Vin=5V and 12V / Vout=0.75V with TPS56C215 EVkit
Vin=5V is more efficient than Vin=12V as datasheet mentioned.
1) Is there any reason why Vin=5V is more efficient? …
Part Number: TPS56C215 Hi,
I have a question about TPS56C215 mode pin resistor setting.
According to datasheet, When I set FCCM, ILIM, 1200kHz mode, the Rm_H is 180k and Rm_L is 51k.
But When I set the same mode with WEBENCH power designer, it use different…
Part Number: TPS56C215 I have a question about TPS56C215.
According to the datasheet, it is mentioned that, under the same conditions,
the switching frequency increases as the output voltage(Vout) decreases for a same input voltage(Vin).
As I know, by…
Part Number: TPS56C215 Hello Tier,
I have a question about the Valley current limit in TPS56C215. I'm afraid of misunderstanding, so I edited a figure in the E2E post for your reference. Can you tell me if the waveform below explains the Valley current…
Part Number: TPS56C215 Hello,
How can I perform stability (Bode plot) analysis of TPS56C215? I cannot find the menu "Bode Plot" in WEBENCH.
Best regards, Shinichi Yokota
Part Number: TPS56C215 Hello,
I'd like to know the operation state when Rm_l and Rm_h are set to the following case.
case 1: Rm_l = 20k ohm, Rm_h = nothing (removed)
case 2: Rm_h = 120k ohm, Rm_l = nothing (removed)
