Part Number: TPS922052 Tool/software: Hi
May the 2 PWM-signals for the flexible dimming mode different in frequency and phase to each other? Figure 8-4 in the datasheet shows 2 equal signals - maybe just for explanation?

Part Number: TPS922052 Other Parts Discussed in Thread: LM3406 , , TPS92515HV , TPS922055 , LM3409 , TPS92515 Tool/software: Hi, we currently get excellent dimming performance from an LM3406 with an externally managed shunt, we would however like to be…
Part Number: TPS922050 Other Parts Discussed in Thread: TPS922052 , Tool/software: Hello,
it is about the D2 (analog dimming) devices, TPS92205xD2.
As i understand it from the datasheet, the analog dimming method is "real" analog dimming.
But the…

This is Krupanand, I have quick question about TPS922052 IC. I am looking for some simulation models like TINA based. Do you support this? if not, how I can…
Part Number: TPS922052 Other Parts Discussed in Thread: TPS92511 , Hello guys,
One of my customers is looking for LED driver which can be used for the following conditions.
Topology: 1channel Buck VIN: 18V~40V LED total Vf: 9~11V Iout: 100~200mA Dimming…
Part Number: TPS922052 Tool/software: The datasheet says that it can be used as a battery charger.
But there is no sample circuit diagram for a charging circuit in the datasheet.
Could you please provide a sample circuit diagram for a battery charging…
Part Number: TPS922052 Tool/software: Configuration is as follows:
- Bridgelux 18v/500mA COB - PWM @ 1kHz, 9-bit resolution - Analog @ 20kHz, 8-bit resolution
Using PWM mode, I can get the LED to dim down to duty cycle 2/512. If I move from duty cycle…
Part Number: TPS922052 Hi,
Could you please tell me the specifications ( rated voltage / current) of the diode required when using the TPS922052 with an input of 24V and an output current of 2A?
FSV12100V was used on EVM.
