Can the enable line be pulled to Vout instead of Vin? Datasheet only gives EN input current spec when pulled to GND of Vin (Vin < 1.5 V). If enable can be safely pulled to Vout, are there any consequences such as increased EN pin current?
Other Parts Discussed in Thread: TPS61221 , TLV61225 Hi folks,
The following is my layout for TLV61225 / TPS61221. I would like to borrow your eyes to have a look at the layout and see if it confers any EMI problem.
The reason I ask is, I don't quite understand…
Other Parts Discussed in Thread: TPS61221 , TLV61225 From their datasheets the TLV61225 and the TPS61221 look nearly identical. Could someone please describe the differences between them, and what might make one better for a particular application than…
Hello Lefteris,
Please see the following document https://www.ti.com/lit/ug/tidu378a/tidu378a.pdf chapter 4.2. This is for the RF430CL330H but can be used also in your case. For higher supply voltages a low power DC/DC converter can be added (e.g. TLV61225…
Other Parts Discussed in Thread: TPS61221 , TPS61220 Hi,
my customer evaluated TPS61221 for a regulator 3.3V / 70mA from a battery (0.7V). The power is produced for small RF key and the customer says that with TPS61221 the range of RF key dropped dramatically…
Hi Ugnius,
yes, this approach to harvest more energy is also possible for the RF430FRL152H. Please see the following document chapter 4.2. This is for the RF430CL330H but can be used also in your case. If it is possible to get the required 1-2mA depends…
Part Number: TPS610981 Other Parts Discussed in Thread: TLV61225 , TPS61098 , I'm looking at the TPS610985X family of chips and am having some trouble figuring out which is best to use. My average load current is about 20 uA, peak current is 10 mA. I'm running…
Part Number: TPS61021A Other Parts Discussed in Thread: TLV61225 Hi Support team
Working with a customer on an issue with the TPS61021a. I am working on getting the schematic, however this is hot. They are having an issue getting it to stabilize driving…
Other Parts Discussed in Thread: TLV61225 , TLV61224 , TPS61220 Hi Team,
The customer is looking for an EVM to evaluate the TLV61224. I have checked and it doesn't seem this is available for either the TLV61224 adn TLV61225.
Is there any solution for…
