The SGM66023 is a high power density synchronous Boost converter with 3.5A (TYP) valley current limit. The device supports wide input voltage range from 0.5V to 5.5V which is suitable for various input source type, such as Li-Ion battery, multiple alkaline batteries in series, and super capacitors. The device is capable of operating down to 0.5V input voltage after startup which is beneficial for maximizing the input source utilization.
The SGM66023 operates with 1MHz switching frequency at input voltage above 1.5V to allow the use of small inductor. The switching frequency folds back gradually to 0.5MHz as the input voltage drops from 1.5V to 1V. The device enters power-save mode at light load condition to maintain high efficiency over the entire load current range. The device consumes 24μA (TYP) quiescent current from VOUT in light load condition.
The SGM66023 provides various protection features such as over-voltage protection, short-circuit protection and thermal shutdown protection.
The SGM66023 is available in a Green SOT-563-6 package.
