Part Number: TPS82130 Other Parts Discussed in Thread: TIDA-01457 Hi Expert.
My customer is willing to use TPS82130 in their new project for negative output. I promote TIDA-01457 and I have a small question. Will our design have any impact on the system…
Part Number: TIDA-01457 Other Parts Discussed in Thread: TPS82130 , Hi team,
In the datasheet of tps82130 the thermal derating curves are available for common output voltages like 3.3, 1.8, 1.0.
However, my customer is curious to know these values if the…
Part Number: TIDA-01457 Other Parts Discussed in Thread: TPS82130 , TPS62130 Hi Experts,
Just like TIDA-01457 and SLVA514B, the artical, from below picture, point out that ' flowing through the body diode pulls the VOUT pin below IC ground , which violates…
Part Number: TIDA-01457 Other Parts Discussed in Thread: TPS82130 , , TIDA-01405 Hi Team,
Recently we are using TPS82130 as IBB. Their schematc is very close to below, except Cout is only 22uF.
My questions below:
Why there is no Cbyp between VIN and…
Hi Ryan,
I think it might be easier for you to start with TIDA-01457.
Generally, you can use a buck converter for positive to negative conversion.

Part Number: TPS82130 Other Parts Discussed in Thread: TIDA-01457 Hi
I ran into an issues with TPS82130 used as in inverting configuration in our designed boards as suggested in TIDA-01457. Please see the below schematic. I am using 12V as Vin. we designed…
Hello,
For the TPS62913, it is not recommended to have a VIN-VOUT cap (sometimes called CIO or CBP) due to the stress it can cause on the VO pin. If you find you need to use a CIO, it is recommended to use a diode across the output as shown in the following…
Part Number: TPS82130 Other Parts Discussed in Thread: TIDA-01457 Hi Team,
We can use TPS82130 to generate a fixed output voltage. It has been done in the reference design TIDA-01457
My question is: How to add VDAC to generate adjustable negative output…
Hi Kevin,
Thanks for sending your specs.
Here is a design that I happen to know of for the +5Vin to -5Vout: https://www.ti.com/tool/TIDA-01457
Let me check with others for more solutions for higher output voltages.
Thanks,
Chris
Part Number: TPS82140 Other Parts Discussed in Thread: TIDA-01457 Hello,
I'm trying to figure out the PSM/PWM crossover frequency of the TPS82140 when used in an inverting buck/boost configuration similar to TIDA-01457.
My design parameters are…
