Part Number: LMX2594 Other Parts Discussed in Thread: TPS62150 , TPS62821 , TPS62825 Hello,
What point should we consider parameter to select power supply for LMX2594?
TPS62150 is on the EVM but I think TPS62821 or TPS62825 is better option because…
Hi Dan,
we don't have pin-2-pin alternatives to TPS5420 in our low-VIN portfolio to my knowledge.
Here are some alternative low-VIN bucks, that can all be used with a 5V input and generate 3.3V and 100mA output:
- TLV62568 (available in SOT23 and…
Thanks for confirming.
The TPS62088 D/S shows 92.5% efficiency at that operating point.
TPS62821 shows 95%.
If you can start a private 'conversation' with me, please share the customer and application and why they really want to use TPS62088…
Hi Sakai-san,
If efficiency is the goal, then the lower frequency TPS62821 may be a better, though larger, choice.
As well, the efficiency strongly depends on the inductor used. There is more variation from this component than from temperature.…
Hi Ben,
A buck converter in an inverting buck-boost topology can be made by following this reference design: TIDA-01405 , different buck converters can be used in place of the one given in the reference design.
The least time consuming design should…
Hi Sakai-san,
By searching the forum with just 'TPS62230', this is the first post that came up: e2e.ti.com/.../627360
Please use TPS62821 or TPS62088 if you need to adjust Vout during operation.
Thanks for explaining.
We need to avoid any extra inductance in the input cap routing, which handles the switching currents.
The TPS82130 is a different device from a different design team, so it won't necessarily have the same issue as another…
Daniel,
Unfortunately, if the efficiency curves are not available in the datasheet then they cannot be provided.
In this case, I doubt a PMIC will have the efficiency you require at light loads (>90% efficiency for 10mA-35mA loads in a buck converter…
