Part Number: LM3642 Hi Team,
In datasheet, it mentioned Vin range is 2.5V min.
And UVLO is 2.8V typical.
So does it mean when UVLO function is disabled, then Vin can support as low as 2.5V for start up? Thanks.

Part Number: LM3642 Hi team,
I wonder the current accuracy when the output current is around 100mA(in torch mode the output current is 93.74mA and 140.63mA). In datasheet the accuracy is 10% when the output current is 48mA. Is the accuracy higher when…
Part Number: LM3642 Other Parts Discussed in Thread: LM3643 , LM3544 Hi team,
My customer is looking for the alternative of AW9523BTQR，AW36423FCR，OCP8132AVAD(need P2P and good supply)
Can you help check this issue?
Thanks

Part Number: LM3642 hi
I would like to ask about the LM3642 design as follows.
1. Development progress - Control by I2C communication, HW pin such as STROBE, TX / TORCH etc. is not used. - It is implemented in order of about 1.2A -> 350mA -> 350mA…

Does TI have Camera flash LED support hardware control LED current IC?
ILED is 350mA & 1000mA.

Part Number: LM3642 Hi team,
My customer is trying to enable torch mode by changing register(0x0A) to 0x02 (torch).
1. They tried to send (0x0A) to 0x02 (torch), but the LED is not lighted up, then they read back register 0x0B is 0x05.
2. They tried…
Part Number: LM3642 Hi,
I'm using LM3642 as the LED driver for the camera, and programed below two registers
0x2 --> Enable Register (0x0A)
0x70 --> Current Control Register (0x09)
but when I measure LED pin using the scope, the output is 0V…

Hi Team, I would like to ask two questions. 1) I believe the following LED efficiency include the efficiency of boost converter. Is my understanding correct? 2) Does TI have the LED efficiency data under VIN=2.5~3.5V (especially…
Part Number: LM3642 Other Parts Discussed in Thread: LM3648 , LM2759 , I am designing a led driving circuit for LED Luxeon LXML-PWC2. LXML-PWC2 forward voltage is 3.1V at current 1A. I am planning to drive it at 700mA, where the led voltage would be 3V…
