Part Number: TPS92520-Q1 Hello Expert,
I'm trying to use two TPS92520-Q1 on TPS92520-EVM133 in Daisy Chain configuration. In single usage, everathing form current setting to pwm setting and activation of channels is working completely fine. In Daisy…
Part Number: TPS92520-Q1 Hi team,
My customer got some questions about open load detection, they found OL cannot be triggered stably.
There is a diagram in E2E as below:
Case1: TOFFMIN =1, COMPOV = 1
Case2: TOFFMIN =1, BSTUV = 1, ( HSILIM = 1…
Part Number: TPS92520-Q1 30 kHz frequency is seen when measuring wire connector pin with oscilloscope after output of pcb on pcb using TPS92520-Q1. I want to know the cause of this frequency. The switching frequency is 450 kHz. Is it caused by internal…
Part Number: TPS92520-Q1 Other Parts Discussed in Thread: TPS92520EVM-133 I had previously opened a case. CS3154752: Issue with TPS92520EVM-133.
You choose to move it to the forum and close the case.
I had a few exchanges with Francis Houde on the…
ILED_REF_DACx outputs a scaled version of the V DAC(FS) voltage = 2.45V as the reference to the input of the current sense amplifier. There is a circuit shown in the block diagram that takes that reference voltage and divides it by 14 at the Vcsp-Vcsn…
Part Number: TPS92520-Q1 Hi team,
Customer is using internal PWM dimming, UDIM is connected to VCC, now they want to decrease the dimming duty to 0 to turn off the lighting, but it is listed MIN is 4% in the datasheet, why is this and how to turn off…
Part Number: TPS92520-Q1 Hello team,
My customer plan to use this device in grill lighting, below are some usage requirements:
Disabling SPI Communication: Completely disable the SPI interface and ensure the device operates without any SPI initialization…
Part Number: TPS92682-Q1 Other Parts Discussed in Thread: TPS92520-Q1 Hello,
I'm working on a IC that holds both TPS92520-Q1 buck converters and one TPS92682-Q1 boost converter (used in CV-mode) connected alltogether through SPI in daisychain configuration…
Part Number: TPS92520-Q1
Tool/software:
Hello, Experts.
We tested the open circuit test of TPS92520 and found that sometimes the open circuit fault cannot be reported.
We have already done it according to this detection logic, and there is still…
