ZHCSE17B July 2015 – November 2017 LM43601-Q1
PRODUCTION DATA.
For highest efficiency of operation, TI recommends that the BIAS pin be connected directly to VOUT when VOUT ≥ 3.3 V. In this self-bias mode of operation, the difference between the input and output voltages of the internal LDO are reduced and therefore the total efficiency is improved. These efficiency gains are more evident during light load operation. During this mode of operation, the LM43601-Q1 operates with a minimum quiescent current of 36 µA (typical). See VCC, UVLO and BIAS for more details.
