STBB1-AXX 1 A, high efficiency single inductor dual mode buck-boost DC-DC converter Features ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Buck-boost DC-DC converter Operating input voltage range from 2.0 V to 5.5 V 2% DC feedback voltage tolerance Synchronous rectification Shutdown function 1.5 MHz switching frequency Power save mode at light load Typical efficiency: > 94% 1 A output current capability Shutdown current < 1 µA Available in DFN10 (3 x 3 mm) integrated low-RDSon N-channel and P-channel MOSFET switches contribute to its high efficiency. The MODE pin allows selecting between auto mode and forced PWM mode thus taking benefit either of lower power consumption or best dynamic performance. The device includes also soft-start control, thermal shutdown and current limit.
