TPS92630-Q1: Maximum output current question

Part Number: TPS92630-Q1
Other Parts Discussed in Thread: TPS92633

Hi Team,

The customer wants to check the maximum output current when applying it to the vehicle LED module.

Spec : 

- Input voltage condition: min 9V ~  max 16V

- Consumable load conditions: min 5.7V ~ max 7.5V

Q1 : TPS92630 IC controllable current range under load conditions.

Q2 : Why DATASHEET can be controlled up to 450 mA (CH individually 150 mA) but not the actual product?
- When designing actual products, control CH individual 50mA and 150mA total. (Heat issue)

Q3 : Please advise the necessary circuit environment to control up to 450mA.

  • Q1 : TPS92630 IC controllable current range under load conditions.

    50mA per channel

    Q2 : Why DATASHEET can be controlled up to 450 mA (CH individually 150 mA) but not the actual product?
    you should condier the device can normally work in 85deg condition

    Q3 : Please advise the necessary circuit environment to control up to 450mA.

    series resistor on output, three channel parallle, or consider tps92633
