Part Number: TPS628502-Q1 Tool/software: Our company uses the TPS62850240QDRLRQ1 for our products. In extreme cases, if the TPS62850240QDRLRQ1 cannot be procured, can the TPS62850240QDYCRQ1 be used as a substitute for the TPS62850240QDRLRQ1 without changing…
Part Number: TPS628502-Q1 Hi Team,
Posting on behalf of our customer.
There is "input overvoltage protection“ feature in the datasheet of TPS628502-Q1, chapter 8.4.7
Does that means, if the input voltage in VIN exceeds the absolte maximum rating…
Hello,
I have reviewed the TPS628502-Q1 schematic. Please find my comments:
Datasheet recommend 18uF minimum effective capacitance (considering derating and tolerance). In schematic, I see nominal 2x10uF, so after derating and tolerance, effective…
Part Number: TPS628502-Q1 I am using TPS62850208QDRLRQ1 in my new product developement. It is used to convert 5Vdc to 3.3Vdc, however we find that even without loading/ a small load (~10mA), the IC temperature already has 8C temperature rise and the efficiency…

Dear TI support,
We are using TPS628502QDRLRQ1 as Buck from 3V3-1V2 with current output load up to 2A
Here below the detailed schematic
We observe 3 unexpected behaviors according to the configuration…
Part Number: TPS628502-Q1 Hi Team,
As datasheet said, when the lod current reach out to current limit, it will clamp the current for 1024 switching cycles and lower the current for 3072cycles. According to our test results, 1024 cycle clamping is…
Part Number: TPS628502-Q1 Tool/software: Dear TI's team members,
Driving Condition for LV-Buck PWM IC :
Input Voltage = 3.3V
Output Voltage =1.15V
Load Current (max.) = 0.1A ~ 2A
Voltage Ripple = (+/-) 25mV
We uses SIMPLIS Simulation Tooling…
Part Number: TPS628502-Q1 Tool/software: Hi Team,
In datasheet, TPS6281x-Q1 effective Cout suggestion is 22uF and TPS62850x-Q1 is 10uF. But they are using the same control theme. (peak current) I am not sure why we have two different suggestion for…
Part Number: TPS628502-Q1 Hello team,
We are supplying 1.1V voltage using TPS62850240QDRLRQ1 to CYT4D infenoen microcntorlle. This micrcontroller have internal voltage reulator also whihc is on in sleep mode. output of TPS62850240QDRLRQ1 and internal…
