Part Number: LMR14010A
Other Parts Discussed in Thread: TPS560430

Hello support team,

My customer would like to know a threshold current to exit the ECO-mode from no load.
They are using LMR14010AEVM with Vin=24V and Vout=5V.

Thanks and regards,
Kaizawa

Hi Kaizawa,

The threshold current is related to the circuit parameters. IC judges according to the internal Comp logic , not the load current.

Kaizawa,

The load current is about 100mA to exit Eco-mode for most case, it depends actual application design as smaller inductor has lower threshold

Team,

One more question.
Can user disable the Eco-mode?

Hi,

LMR14010 Eco-mode can't be disabled at light load condition, you can try TPS560430 if require fixed Fsw at light load.
