Hi User,
Yes, this agrees with the current limit behavior described in section 8.4.4 of the D/S. Hiccup or latch off is not mentioned, so it should not be expected to behave this way.
The TPS62821 is a newer, smaller, and more efficient device and…
Hi User,
This is a power management device, but this is the amplifiers forum. Just FYI.
The output voltage tolerance is shown in the D/S on page 7, under 'output voltage accuracy'.
The device's current limit limits the output current, as explained…
Hi Phil,
That note just keeps the IC out of 100% mode, for purposes of the accuracy specification. In 100% mode, Vout just follows Vin, since Vin is too low. Thus, the output voltage will drop.
But this is an older IC. Why not use the newer TLV62568…
Hi zhang ping,
The MP1495S can also be replaced with TPS62130 (there is 3.3V version TPS62132 to reduce the two FB resistors)
The MP2162 can be replaced with the TPS62821 or TPS62825.
The MP2143 can be replaced with the TLV62585.
The MP1605C can…
Hi Dibin,
Nick correctly addressed why the recommended operating conditions table is written that way: this device has a higher Rdson which prohibits meeting the requirements of some higher current, lower dropout applications. Let us know if there…
Hi,
An alternative part must also be cheap, have accuracy closer to +/-1% and large pitch footprint as in the SOT23 0.95mm pitch package (not 0.5mm).
Hence LM3691 or TPS62821 are not possible for instance.
- Can you tell me what happens on the TPS560200…
Hi Vasily,
If you have a 5V input, there are generally more optimal solutions. See TLV62585 for 3A and TLV62568/9 for 1A and 2A options.
If you need better transient response, see the TPS62821/2/3 family.
Hi Cooper,
Please see the pin functions table on the next page and section 8.3.2 which explains this column.
This device family does not have output discharge. So, when it is disabled, Vout might remain at some value, if there is insufficient leakage…
Hi Joe,
The device's current limit will limit the output current to safe value. This app note explains how this works (for a different device) in section 4: www.ti.com/.../slva543.pdf
25 msec is DC to the device, so it will enter current limit if…
Hi Dave,
I have been trying to figure out the possible causes of this issue but I could not come up with something. Therefore, I would like to ask you to go through our FA procedure, which has to happen through the local distributor who provided the…
