ZHCSIT4B September 2018 – April 2024 LM5164-Q1
PRODUCTION DATA
EN/UVLO provides ON and OFF control for the LM5164-Q1. When VEN/UVLO is below approximately 1.1 V, the device is in shutdown mode. Both the internal linear regulator and the switching regulator are off. The quiescent current in shutdown mode drops to 3 μA at VIN = 24 V. The LM5164-Q1 also employs internal bias rail undervoltage protection. If the internal bias supply voltage is below the UV threshold, the regulator remains off.
