Hi support team,

For this Buck , what is the EN pin sourcing pullup current for calculating Rent resistors for regulating the enable pin, with voltage divider. It is specified as a small current! what would be the range or value for Ip.

Hi Sowmiya,

The sourcing current is about 1.5 uA when Ven=1.1 V and about 11.6 uA when Ven=1.3V.

Hope this helps.

Hi sir,

The values for Ip and Ih is still in a dilemma, as it is not mentioned for either pullup or hysteresis ( it is been simply denoted as EN pin sourcing current)

May i know the value for pullup current sir (Ip)

Hi Sowmiya,

Ip is typically 1.5 uA.
