Part Number: TPS62840 Dear TI Team,
We are using TPS62842 buck converter and our setup is following:
V input = 4.2V
Rset = 52.3k (Desired Vout = 3.3V)
MODE Pin -> Connected to GND ( Low power mode)
EN Pin -> Connected to HIGH (Enable device operation…
Part Number: TPS62840 Dear Team,
The current expected use environment is: power supply using two CR2032 series power supply,
In actual use, there will be abnormal situations where the battery is reversed connect.
After the battery is reversely installed…

I want to use the TPS62840 in my project with an input voltage of 6.2V and an output of 1.8v. The output voltage will be connected to an MCU and one temperature sensor. The peak current of my devices is around 24 mA(20mA + 4mA…
Part Number: TPS62840 Hi, Good day. Our customer have several question regarding the TPS62840. 1. Under-voltage lockout, how we get into it and how we get out of it? 2. So you have a hysteresis for when lock out starts and when you get out of it? 3. What…
Part Number: TPS62840 Team, I would like to know the state (high impedance, high, low) of the SW pins when either the EN or RUN/STOP signals are activated. The idea is to use one of those pins to disconnect the tps62840 from the rest of the circuitry…
Part Number: TPS62840 Hello,
I can see on the TI web site that the TPS62840DLCR product status is active but also that there is no stock
and no samples available (and the status is the same for the DSBGA package).
Would you please tell me when samples…
Part Number: TPS62840 The datasheets will show only power saving mode IQ current but there is not mentioned any current when the device is switching could you please tell the current consumption of TPS62840 when the buck is switching?
Part Number: TPS62840 Dear Sirs,
My customer use TPS62840 for 3.3V output to their system.
He found while the system in standby mode and the TPS62840 Vin is 3.36V~3.39V, the current consumption will increase 600~900uA.
If the Vin is higher than this period…
Part Number: TPS62840
For an application that needs small start up time:
Datasheet SLVSEC6D gives at page 8: tSTARTUP_DELAY: 10 ms typ. tss: 120us typ.
Can we share some worse case value (ie max startup and tss timing) base on qualification? This…
Part Number: TPS62840 The datasheet specifies a startup time of 200us unless the Enable signal ramps with Vin. Just at specified in the datasheet we have a delay of 2ms (10ms MAX) when Enable ramps with Vin, however the delay is about 2.7ms after Enable…
