8A Valley Current, 0.5V Ultra-Low Input, Synchronous Boost Converter

The SGM66022 is a high power density synchronous Boost converter with 8A (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 SGM66022 operates with 1.2MHz switching frequency at input voltage above 1.5V to allow the use of small inductor. The switching frequency folds back gradually to 0.6MHz as the input voltage drops from 1.5V to 1V. The device implements a MODE pin to configure forced PWM mode or auto PFM mode at light load condition. The 30μA (TYP) quiescent current into VOUT pin maximizes the light load efficiency.

The SGM66022 provides input disconnect feature during shutdown. In addition, various protection features such as over-voltage protection, short-circuit protection and thermal shutdown protection.

The SGM66022 is available in a Green TDFN-2×2-7AL package.
