Part Number: TPS61221 Other Parts Discussed in Thread: TPS61322 , TPS61299 Hi, I'm designing a battery power device (2 alkaline) that will sleep for 5-10 minutes, wake up for a few seconds, collect some information and sleep again.
The device uses…
Part Number: TPS61221 Hello,
I'm designing a product that is powered by two AA batteries and a TPS61221 is used to supply 3.3V to a bluetooth module.
The BT module is only use in certain conditions and most of the time is powered down by bringing…
Part Number: TPS61221 Other Parts Discussed in Thread: TPS61299 , Hi,
the following thread said " The output voltage will track the input voltage. As Vin goes higher, Vout goes higher. There will be a voltage drop across the IC that is a function of…
Part Number: TPS61221 Other Parts Discussed in Thread: TPS63031 , TPS61220 Hi,
am using diode ORing circuit before TPS61221.
so TPS61221 has input either 3.3V (battery) or 5V(USB).
is it ok to operate TPS61221 with USB voltage? do you see any potential…
Part Number: TPS61221 Hi,
We are planning to use the TPS61221 as the Boast voltage regulator for 3.3V. Here the input voltage is coming from non-rechargeable battery coin cell battery(CR2032R) and it varies the input voltage is 3v to 1.2v during its…
Part Number: TPS61221 Other Parts Discussed in Thread: TPS61261 Hello urgent help required I have designed a power supply using TPS61221 Booster IC, Input supply is 3V and required output voltage is 3.3V , 7mA. CR2025 coin cell is used to drive circuit,…
Part Number: TPS61221 Other Parts Discussed in Thread: LMR70503 , TPS62745 Hi team, Could you give me your advice about the output negative voltage? My customer wants to output 3.3V negative voltage with 3.3V input. The output current is very low(Around 1mA…
Part Number: TPS61221 Hello,
I'm using Tina for simulated my circuit. I taked the spice model on TI site here: http://www.ti.com/product/TPS61221/toolssoftware
But it seems to be encrypted, some know how to decrypt it.

Part Number: TPS61221 Other Parts Discussed in Thread: TPS61291 Hello,
We have a small, low-power device with a sub-1GHz transceiver and MCU (CC430F5xxx series), where power is supplied from a coin cell (CR2032 and/or CR2450) battery. The device sleeps…
Part Number: TPS61221 Hi there,
I designed a PCB board for TPS61221 according to the datasheet.
It successfully delivery 3.3V at Vout.
The circuit is as below.
However, I found that while no load at the output. The I in (input current) is about 6…
