SNVSA44B August 2014 – January 2018 LM43601
PRODUCTION DATA.
The LM43601 is in active mode when VEN is above the precision enable threshold and VCC is above its UVLO level. The simplest way to enable the LM43601 is to connect the EN pin to VIN. This allows self start-up of the LM43601 when the input voltage is in the operation range: 3.5 V to 36 V. See Enable (ENABLE) and VCC, UVLO and BIAS for details on setting these operating levels.
In active mode, depending on the load current, the LM43601 is in one of four modes:
