Part Number: TPS61261 Hello, we have run into some issues with the TPS61261 boost converter. We have noticed that if the regulator is enabled after a certain delay from the previous disable, it will ignore the enable signal. The problem seems to be strongly…
Part Number: TPS61261 I have a design where I'd like to have a second (5V) power supply in parallel with the output of a boost converter (1.2V NiMH to 3.3V). The goal is to have either power source feed the device. Will the TPS61261 converter be harmed…
Part Number: TPS61261 Other Parts Discussed in Thread: TPS61322 , TPS61099 Hi
I am attempting to create a Temperature sensor that uses WiFi to upload a reading once per minute.
The transmission/upload time period is probably around 5 seconds and then…
Hi Zhonghui,
The structure of TPS61261 is fixed, the LSFET is NMOS means that when input gets inverted polarity, the current will flow from LSFET's source to drain through its body diode. This means short circuit from GND to SW and this could damage TPS61261…
Part Number: TPS61261 Other Parts Discussed in Thread: TPS61023 , TPS61094 why set 2 NMOS in series at the high side of TPS61261?
Refer to datasheet, My understanding is that:
1.The R-on resistance of the right-NOMS play the role of Current sampling resistor…
