Part Number: TPS922052 Other Parts Discussed in Thread: TPS922050 Posting on behalf of my customer:
I’m looking for an LED driver IC that can be used to drive a single LED at a constant current of 15-30mA. Preferably a switching regulator instead of…
Part Number: TPS922052 I used the TPS922052 to test the LED driving current. After a 24-hour test, the current fluctuation was significant. Please analyze the root cause based on the normalized data.
Part Number: TPS922052 Other Parts Discussed in Thread: TPS922050 , TPS922051 , TPS922054 Tool/software: Hi Teams,
I have a customer here who has the following requirements, I need to consult about the LED driver chip for the infrared fill light of…
Part Number: TPS922052 Other Parts Discussed in Thread: LM3409 , TPS922051 Tool/software: Hello, we are using tps922052 for optical pulse output. It takes more than 2ms to light up the LED with this chip for the first time, but we would like the rise…
Part Number: TPS922052 Hi
Performs the device a complete shutdown at Ttsd=typ 165C even the thermal foldback function is not used and disabled (TEMP pin to AGND pin)?
Part Number: TPS922052 Hi
I noticed with our 4-channel design (attached), that the LED-current at a specific value/dimm level shows a ripple (attached). Above and below this current, the output current is stable. Any explanations? Input/output capacitor…
Part Number: TPS922052
Tool/software:
Hi,
we're using the TPS922052 in an LED driver. We had an issue with the LEDs glowing when turned off , which we resolved by adding a high-ohmic shunt resistor (as suggested in this forum).
Now we're trying…
Part Number: TPS922052 Tool/software: Hi Team,
In our design, we have used TPS922052 part to control the brightness of an LED. we are able to achieve it by using the PWM signal. But our agenda is to control with the potentiometer which is not happening…
