Part Number: TPS61097A-33 I'm using the part as specified (L = 4.7uH, C1-2 = 22uF) with a P13-sized Zinc Air cell to boost ~1.45V to 3.3V. I can use my BLE MCU (CC2652) to perform a blink routine but it fails to power up when using the radio. Is this…
Part Number: TPS61097A-33 Hi Team, I would like to seek your insight into this matter.
I used 20uF input cap and 4.7uF output and also tried 10uH inductor, it still does not provide 3.3v at the output. Here I would like to clarify that on No load, I…
Part Number: TPS61097A-33 Hi Team,
After 2.4V voltage input to the VBAT, the LED 8EA (5 seconds) operation produces a lot of voltage drop and enters CUT OFF.
Is there any way to minimize the voltage drop on the DC/DC side?
1. Check voltage drop using…

Hi
The customer was using the TPS61097A-33 for remote control.
TPS61097A Schematic : There is no problem with the boost action.
Input Voltage(VBAT) : 3V(AA*2)
Output Voltage : 3.3V
LED 1ea : 2mA
We designed to add Voltage detector…
Part Number: TPS61097A-33 Other Parts Discussed in Thread: TPS61291 Three separate questions:
1) Is there any time delay from the time the EN pin is taken low to the time the bypass switch is engaged? I am concerned about the energy from the output capacitors…
Part Number: TPS61097A-33 Hello,
TPS61097A-33 is using with one cell battery (1.2 V) and is problem to start. Schematic is a typical connection from datasheet with a recomended parts (Inductor, capacitors).
When I connect to battery, power consumption…
Other Parts Discussed in Thread: TPS61097A-33 Hi All,
I am working on the project using TPS61097A-33 to get 3.3V from 3.6V Li-SOCI2 battery (TL-5955). The system load is dynamic, from 0.2mA to 40mA. With the brand new battery, circuit runs OK. With used…
Part Number: TPS61097-33 Other Parts Discussed in Thread: TPS61097A-33 , TPS61098 Team,
I have a customer currently using TPS61097-33 and are looking at TPS61097A-33 , but notice the that quiescent current is almost twice as high on the newer device. That…
Hi Anupam:
Sorry to notice that:
d. TPS61097A-33 the current limit is too small.
e. TPS61291 the minimum VIN is 0.9V.
As I mentioned, TPS61201 is a good choice.
Hi Jack,
look like TPS610993 is Ok for this application if the WCSP package is acceptable.
or maybe TPS61097A-33, which has very small shutdown current.
let me if my understanding about the circuit is correct.
1. S1 is off, Q4A off, Q2 is off, the TPS610985…
