Part Number: TPS55289 Other Parts Discussed in Thread: TPS55285 , TPS55287 The description of DISCHG in Table 7-10 of the datasheet is misleading: it talks about shutdown. However, shutdown resets the DISCHG bit to 0, so DISCHG=1 would never take effect…
Part Number: TPS55289 The reset value of the REF register (0/1h) of the TPS55289 when read via I²C is 0x00d2 rather than 0x01a4 as documented in the datasheet. Yet, the output voltage is 5V when setting OE to 1. Apparently, there are two copies of that…
Part Number: TPS55289 Tool/software: Dear Team,
We are evaluating the TPS55289 for use in one of our medical device designs. The device is intended to power a Murata micro pump , which requires an operating voltage between 5V and 15V . We are using…
Part Number: TPS55289-Q1 Hello TI Team,
I am currently evaluating the TPS55289-Q1 for use as a USB PD power source, and I would like to confirm several points regarding its operation and characteristics. Could you please help clarify the following items…
Part Number: TPS55289 Tool/software: Dear TI's team members,
Driving Condition for Buck-Boost PWM IC :
Input Voltage = 12V
Output Voltage = 6.5V ( +/-5% )
Load Current (max.) = 1mA ~ 4A
Voltage Ripple = (+/-) 325mV
Could you provide us some…
Part Number: TPS55289 Hello,
We are using this device(tps55289) in our product to charge a 12 volt battery through solar panel. I am trying to figure out if the internal MOSFETs let the current flow backwards? or there is any protection placed in the…
Part Number: TPS55289 Tool/software: Sorry beforehand if this question is easy to answer.
I'm designing a schematic where a DC input goes through a TPS259474 eFuse and then into a TPS55289 buck-boost converter. The eFuse is designed with the design…
Part Number: TPS55289 Tool/software: Good afternoon, We use a TPS25730D in combination with a TPS55289 to create an USB C Power supply. The USB side works fine and can consume upto 100W. The TPS55289 on seems to work fine in the beginning, but fails after…
Part Number: TPS55289 Other Parts Discussed in Thread: INA236 Tool/software: PPS For QA station. (The devices being tested may have short circuit defects, etc.)
The device have input supercap.
V Input: 12V - 2A.
V out :2-5V - from 50uA up to 2A…
Part Number: TPS55289-Q1 Tool/software: Dear TI experts,
My customer asked about dead time of TPS55289-Q1.
Customer's applicaton is highly dependant on switching efficiency, so dead time is very important.
Do you have any document or test results…
