TLC6C5724-Q1: Question about V(out,min)

NOBUO FUJIHARA

Part Number: TLC6C5724-Q1

Hi team,

According to previous E2E thread below, customer expects V(out,min) is less than 0.7V.

But in actual measurement result in attached file shows V(out,min) = 1.6V with "Vcc=5V, Iout=50mA, V_LEDsupply=4.2V" condition..

TLC6C5724-Q1: V(out,min) vs VCC:

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1022070/tlc6c5724-q1-v-out-min-vs-vcc?tisearch=e2e-sitesearch&keymatch=TLC6C5724-Q1%20AND%20V%28OUT%2Cmin%29#

Q1) Could you clarify definition of V(out,min)?

Q2) Could you explain cause why V(out,min) = 1.6V with customer's condition?

Best regards,

Hi,

The V(out, min) is the minimum output voltage for the device to generate the output current.

You can refer to the figure 16 IOUT vs VOUT to know the definition of V(out, min) and get an estimated value. The customer's expectation can be guaranteed.

Best regards,

Gracie
