SNVS579L February 2009 – May 2018 LM26420
The LM26420 features independent precision enables that allow the converter to be controlled by an external signal. This feature allows the device to be sequenced either by a external control signal or the output of another converter in conjunction with a resistor divider network. It can also be set to turn on at a specific input voltage when used in conjunction with a resistor divider network connected to the input voltage. The device is enabled when the EN pin exceeds 1.04 V and has a 150-mV hysteresis.
