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.
Output current: up to 2A (PVIN = 2.5V, VOUT = 3.3V).
Burst current: up to 3A (PVIN = 3V, VOUT = 3.3V, tON < 600µs, t = 4.6ms).
High efficiency: up to 96%.
35µA quiescent current maximizes light-load efficiency.
2.5MHz switching frequency minimizes external compon.
