Power Management ICs Forum Discussions

Hi team, I am having trouble designing 64-watt ballast as I need to design a ballast that can drive 2 32-watt T8 lamps with a preheating time of 2 seconds and running frequency of 45 to 50 kHz but reference circuit provided in the datasheet and App note are for 1 54-watt  lamp. to drive the multiple lamps I need the find the inductor or transformers value which are not present in the datasheet or App note.

I want to use VCC2 for VCAN, so I want to turn VCC2 ON, and since VCP is not used, I want to turn it OFF.

In such a case, should I just make the settings in SBC Init Mode? Is there anything I should be careful about?

(For example, do I need to change any settings when going into Sleep Mode?)

Thanks,
Tetsuo

Absolute maximum ratings VCC supply voltage(Max.) of ICE5GSAG is 27V, please tell me what is the actual measured value?

I'm trying to write PXM1310C with the PowerCode program, but I don't know how to use it.
(Use PX-DNGL-01 dongle)
Please me how to write or manual.

I am writing to inquire about the Voltage Regulator 1 (VCC1) of the TLE9263BQV33, specifically in relation to the Body Control Modules (BMC) board.

On page 42 of the TLE9263BQV33 datasheet, it is indicated that the VCC1 has a low-power mode regulator (VCC1,out71) that operates with lower accuracy during SBC STOP mode for small loads. Additionally, it is noted that a high-power mode regulator is also engaged to support optimal dynamic load behavior as the load current increases.

I have a few questions regarding this:

1. Does the internal structure of VCC1 incorporate two regulators, with one having low current consumption and lower output accuracy, while the other features higher current consumption and better accuracy?

2. Considering that the RF module used in my BMC board has peak current consumption of up to 15mA in pulse form at SBC stop mode, can the VCC1 output dynamically supply this load, transitioning between its low-power mode and high-power mode?

3. The datasheet specifies that the typical current consumption of VCC1 in the high-power mode is around 2.9 mA. Is this current consumption constant irrespective of the output load current? Or does the current consumption of the regulator vary based on the load current? If there is a relationship between the load current and the regulator's current consumption, could you kindly provide a diagram or formula to illustrate this?
