Ultra-Low IQ, Low-Noise 3.5W Buck-Boost Converter MAX77348A, MAX77348B General Description The MAX77348 is an ultra-low quiescent current, noninverting buck-boost converter capable of supporting up to 3.5W output power. The device employs a unique control algorithm that seamlessly transitions between the buck, buck-boost, and boost modes, minimizing discontinuities and subharmonics in the output voltage ripple. The MAX77348 is ideal for a system handling less than 3.5W output power from a single cell Li-Ion battery and requiring high system efficiency with precise voltage control.
