Part Number: TPS610985 Other Parts Discussed in Thread: TLV3691 I have designed an RF energy harvesting circuit which uses the TPS610985. The rectifier device supplying the input voltage to VIN can supply a maximum voltage of approximately 1.2 V, and…
Part Number: TPS610985 I have a design that includes the TPS610985 for supplying 3.0V system voltage from 2xAA Alkaline cells.
On some of my boards I encountered noise related issues. After some measurements I found that some boards had a large ripple…
Part Number: TPS61098 Hello team,
I am wondering what is the current limit in the VBUS output pin in TPS610981 and TPS610986 chipset??? I denoted that load switch on resistance in TPS610985/6 are 1.2Ohm (typical) and LDO dropout voltage in TPS61098/1/2/7…
Other Parts Discussed in Thread: TLV3491 , TPS610985 Hi,
I use TPS610985 and TLV3491 in my project,found that the power consumption is abnormal.Here is the schematic.
(1)The total power of DC/DC is about 5-8uA when R135 is 300Ω. When adjust R135 to 1M,…
Other Parts Discussed in Thread: TPS610985 I have questions .
Mycstomer wants to use TPS610985.
Question 1
Can this IC use inductor which inductance is 47µH~100µH?
Question 2
When we changes capacitance,can this IC set inductance over 47µH…
Part Number: TPS610985EVM-782 Other Parts Discussed in Thread: TPS610985 If I operate the unit at 3V or below, the TPS610985 will drop the output to approximately 2V anytime the Piezo is activated. So, if the TPS610985 is operated in the boost mode it…
Hi Naig:
Understand that, but TPS610985 can't handle 1A.
TPS61023 is closest. But may I know why you can't accept the external resistor? It won't take much cost or solution size.
Part Number: TPS61291 Other Parts Discussed in Thread: LM3370 , TPS610985 RDS(on) of Bypass Switch = 1.2 ohm. Rather high for my liking. Does anyone know of a part with lower RDS(on) besides the TPS6128x family?
Hi Ram,
you can also use a boost converter, but typically the efficiency would be lower and currently there are no other devices on the market, which offer a quiescent current as low as our TPS62840. Therefore I would recommend connecting both batteries…
