Part Number: LM3648 Other Parts Discussed in Thread: LM3643 , LM3644 Dear Sir,
Is the LM3648 LED output pin separately connected to the LED?
Will this design create any other issues?
Part Number: LM3648 Tool/software: Dear Sir,
I have a issue the IC is working but there is no output voltage. I read the IC register 0x0A the value is 0x0004. I kwon IC over heat will cause this register bit to be set to 1. But I check IC surface temperature…
Part Number: LM3648 Hello,
SLVA689–February2015:In this application note why the bus capacitance of Fast Mode plus is given as 550pF ?
Could you please help with this ?
Part Number: LM3648 Other Parts Discussed in Thread: USB2ANY , , MSP-EXP430FR2311 I have a question about LM3648 I2C signal level. Data sheet says VIH min is 1.2V. when pulled up to 1.8V using 1.5k resistors, USB2ANY can't talk to LM3648 when not using…
Part Number: LM3648 Other Parts Discussed in Thread: TPS922052 , TPS923652 , TPS92360 , TPS92390 Hello,
I came across a flash LED driver LM3648, which has the functionality needed for our application.
However, the LED's which we are using require high output…
Part Number: LM3648 Other Parts Discussed in Thread: LM36010 , LM2759 Hi Sir,
If the LM3648 is in thermal shutdown, even if the die temperature is lower than 150°C, the LM3648 is not available for operation until there is an I2C read of the Flags1 Register…
Hi Robin
Could you please help tell me how to get the Pchip of LM3648? The datasheet of LM36010 provide calculation method of junction temperature of LM36010，which is shown in the picture below. I think when the LM3648 is in pass mode, where VIN > VLED…
Hi Zoey,
Sorry for forgetting to reply you!
1.Yes.
2.The VHR is 290mV(typ) when current is 1.5A in flash mode and this is the highest VHR.
3.I'm sorry I can't guarantee the maximum VHR at present.
4.Device will enter boost mode.
Robin
