Part Number: TPS61288 Tool/software: Hello! I'm not clear on how to estimate at what load current the device will switch between PWM mode and PFM mode on the TPS61288. Can you provide some insight? Thanks and Best Regards Jerry Molnar
Part Number: TPS61288 Other Parts Discussed in Thread: TPS61022 Hi Nathan,
Unfortunately our load requirements changed and we've had to evolve away from the TPS61022. We're now planning to go with the TPS62188.
Our load current at 5.5V output is…
Part Number: TPS61288 Other Parts Discussed in Thread: TPS61088 , TPS61089 Hi support team, I am considering changing from TPS61088 to TPS61288 due to current capacity. Therefore, I would like to ask the same question as the original question regarding TPS61288…
Part Number: TPS61288 Hi,
I am designing a backup power supply system with supercaps where leakage currents are very important.
I looked through the datasheet but I couldn't find the leakage current into the SW pin when EN is low. Can you please direct…
Part Number: TPS61288 hi! I made a DC-DC using TPS61288LRQQR . when I put the EN pin low ,Vout=Vin-0.3 approximately, is it correct for it to work this way? shouldn't Vout be =0V when the EN pin is low?. the test I did are with Vin=3.7V, Vin=7.4V, and Vin…
Part Number: TPS61288 Hello All,
I am working on boost converter based on TPS61288RQQR, to be able supply electro locks in pulse mode (power on up to 1 second). Can you check, if my calculations are correct and batteries will handle that? Is PCB design…

Hi Team,
in TPS61089 boost is stated when EN is low and VIN is present and above UVLO:
" Because of the body diode of the high-side rectifier FET…
Part Number: TPS61288 Hi,
The datasheet of the TPS61288 recommends up to 4.7uH, but the Web Bench suggests going to 10uH. Is it a problem going to 10uH?
