Features

Input voltage range: 1.8V to 4.8V.
Fixed 5V or adjustable output.
Output current: up to 1.5A (PVIN = 3.3V, VOUT = 5V).
High efficiency: up to 96%.
35µA quiescent current maximizes light-load efficiency.
True input-output disconnect when disabled.
2.6MHz switching frequency minimizes external component size.
Selectable forced-PWM mode and external synchronization.
Fully protected for short-circuit, over-temperature.
