Part Number: TPS552872 Hello everyone,
I am considering using the TPS552872 in PFM mode in my project. I would prefer not to use FPWM mode because of its relatively high current consumption at idle.
However, with a load of approximately 500 mA, I…
Part Number: TPS552872 Dear team,
My customer used a very special sense resistor - 0.15ohm, because they want to limit the output current to 333mA (50mV/0.15ohm). However, they found this not working, the maximum output current they got is about 620mA…
Part Number: TPS552872-Q1 Hi Teams,
The customer is using TPS552872-Q1 for robot applications, which is used for the first stage DC/DC output 12V of the battery rear stage. Below is SCH, please help confirm if there is any problem? Thank you.
Part Number: TPS552872-Q1 Dear TI Support Team,
We are planning to use the TPS552872-Q1 buck-boost converter in our design. The system input voltage can be either 12 V DC or 24 V DC, and the required output voltage is a regulated 12 V DC. Based on…
Part Number: TPS552872-Q1 Other Parts Discussed in Thread: TPS552872 Hi Please check my TPS552872 schematic, as I am having issues with chip heating and really loud switching.
Part Number: TPS552872 Other Parts Discussed in Thread: TPS629210
Hello all,
I built a board using the TPS552872 to output 12V from 12/24V. There are TPS629210 for 5V and LP5912-3.3 for 3.3V downstream to power some peripherals and the main MCU. …
Part Number: TPS552872 Hello team,
are you able to review the attached schematics?
Remarks:
VIN: 5.0V..28V
VOUT: 7V/1.6A
UVLO: approx. 4.0V

Dear Team,
We are currently in the process of designing a board that requires a power supply with a wide input voltage range. The primary power source will be an…
Part Number: TPS552872 Hello,
I would like to clarify the conditions under which the TPS552872 does not output VCC. With VOUT = 12V, VIN = 0V, EN/UVLO = 0V, and EXTVCC left open, VCC is not output. The datasheet states: "the TPS552872 is in shutdown…
Part Number: TPS552872-Q1 Hi,
I'm trying to use the TPS552872-Q1 to charge a supercapacitor bank.
The input is 24v regulated, once the supercaps are charged output current is <1A.
After misreading the datasheet I had originally pulled EN up to VCC…
