Hi Nikos:
For original boost converter, there is a parasitic diode paralleled the high side switch. So the Vout will remain some voltage if input power is exist.
I believe you are finding a product with true load disconnect function. I'll recommend…
Part Number: TPS61022 Other Parts Discussed in Thread: TPS61099 , TPS61094 Hi,
we have following application: we have to supply a modem which sources in worst case 2Amps @3,6V for a about 3 seconds. In the other time it sleeps and consumes max. 15uA…
Hi Tae:
Thanks for choosing TI.
For first question, the default Vout is 5V for the EVM. If you need 3.3V, you could change the R1 with 573kohm.
For the second one, both TPS61099 or TPS61098x could achieve the target. It seems you don't need the…
Other Parts Discussed in Thread: TPS61099 , TPS61023 , TPS61253A I am looking for a DC\DC Boost regulator 3.3V to +5V Max 200mA (TYP : 50mA) with the smallest PCB area possible. We currently have a ADP2504 that takes a total PCB area of 7mm x 6mm. This…
Yichen,
For the first revision of our design, I am going to use the same inductor as on the TPS61099 evaluation board, DFE252012P-2R2M=P2, as it is a metal alloy inductor and is supposed to have lower audible noise than ferrite.
I was considering…
Hello,
Please take a look at the BQ25121A which is a 300mA charger with a 2.5V DCDC converter which can be adjusted to 3.3V. You can add a boost converter like the TPS61099 to get 5V when on battery only mode
Part Number: TLV61220 Other Parts Discussed in Thread: TPS61099 Hi Team,
I see another thread about below question and feedback,
May I know what is the minimum duty for this device? The TLV61220 works in hysteretic current operation. The current…
