Charge pump regulator for USB power rails
The Maxim Integrated MAX3353EEUE+ is a charge pump regulator IC designed for USB applications, delivering two regulated outputs from an input supply spanning 2.6V to 5.5V. This part generates the VBUS voltage required by USB host or charger ports, or provides a clean bias rail for downstream circuitry. The 16-TSSOP package (4.40 mm width) suits space-constrained boards where a separate inductor-based converter would consume more area.
The wide input range (2.6V to 5.5V) allows direct connection to a single Li-ion cell, a 3.3V or 5V rail, or a USB bus voltage — no external pre-regulator needed. Two independent outputs give the designer flexibility to power separate loads or cascade for higher voltage.
