Note 1:

Limits over the specified operating temperature and supply voltage range are guaranteed by design and characterization,

and production tested at room temperature only.

Note 2:

Output accuracy in low-power mode (LPM) and does not include load, line, or ripple.

Note 3:

This is a static measurement. The actual peak current limit depends upon VIN, VOUT, and the inductor due to propagation

delays.

Typical Operating Characteristics

VIN = 3.6V, VOUT = 1.8V, CIN =10µF, COUT = 22µF, L = 2.2µH unless otherwise noted.
