Part Number: TPS62770 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hello,
I am looking for TPS62770 macro model, but I couldn't find in SMPS TI simulator.
I wonder there is any other device being compatible to 62770…
Part Number: TPS62770 Hey, what's thte threshhold on the /EN pin for the TPS62770. We list a low of 0.4V and a high of 1.2V... can I drive it with 1.2V and get it to turn on? It clearly above to max low; but seems tight on the high level threshold…
Other Parts Discussed in Thread: TPS62770 , TPS62743 Hi TI Experts:
I have a customer that would like to use Buck DCDC, TPS62770.
It have 1 stepdown and 1 stepup output.
The Buck DCDC do have an extreme low Iq but they only need the stepdown output.
According…
For the LED driver, the voltage would be limited by the built-in OVP circuit.
What input voltage do you have? Do you need the buck converter inside the TPS62770?
Just a reminder to title your posts without the word 'question'. Instead, put your…
Other Parts Discussed in Thread: DRV8800 , TPS62770 Hello,
I have a tricky power situation. I have a battery (~3.67V) or external 5V supply line that needs to be split into two buses. One is a 3.0V bus (nominal current is 0.9mA, but can go as high as 100mA…
Other Parts Discussed in Thread: TPS62770 , TPS62748 , TPS62740 Hello everyone,
I have a device i need to power with 1.0 V. It's sensitive to voltage supply variation. I'm concerned to use TPS62770 for this matter. According to the datasheet, the accuracy…
Hi Mike,
For a wearable, there are PMICs with the charger like bq25120 and bq25150.
We also have a boost + buck + load switch in TPS62770.
If you need discrete DC/DCs for higher efficiency, the TPS62743/6/8 and TPS62800 families are very small, popular…
Glad you can use the load switch. If you need a boost as well, please take a look at TPS62770.
We also have TPS62808, if you need something smaller or with more output current.
Hi Zai,
Check out this reference design which charges a super cap with 360 nA Iq: http://www.ti.com/tool/PMP9753
On the TPS62770, the LOAD switch just connects the buck output to the LOAD pin. You can see this in Figure 4.
