LM5116: Device consumption current when UVLO=0V

Shane Ke

Part Number: LM5116

Hi Sir,

There is a description in datasheet as below.

"If the UVLO pin is pulled below 1.215 V, the regulator enters a standby mode of operation with the soft-start capacitor discharged and outputs disabled, but with the VCC regulator running."

How is the device consumption current at this moment? Is it defined as " UVLO Pull-up Current Source, UVLO = 0 V , 5.4 µA "

Hello,

I have discussed with the product expert, and I have checked the performance on the EVM. When the UVLO pin is pulled low, the device will be in standby mode and the current consumption will be in the mA range. For instance, on the EVM when VIN=12V and UVLO=0V and EN is high, the input current is 3.55mA.

If low power mode is required with Iq in the uA range, then you must tie EN low as well.
