In low power consumption applications, the quiescent power consumption and standby power consumption of the power IC itself are more important. Our MAX77650 is equipped with an extremely low quiescent power consumption: 0.3μA standby current; 5.6μA operating current (3 SIMO + LDO).
The 85% efficiency of SIMO is advantageous compared to the scheme of one buck + multiple LDO. Compared to curcuits that comprise multiple DC-DC converters, it also has advantages due to its small size, low cost, and low design complexity of the circuit board. Overall, it provides the best performance balance.
