Features

Accepts input voltages above or below regulated output voltage.
Automatic and seamless transitions between Buck and Boost modes.
Input voltage range: 1.8V to 5.5V.
Continuous output current: up to 2.1A (PVIN = 2.5V, VOUT = 3.3V).
High efficiency: up to 96%.
30µA quiescent current maximizes light-load efficiency.
2.5MHz switching frequency minimizes external component size.
Fully protected for short-circuit, over-temperature.
