Efficiency

VIN = 3.6 V

VOUT = 1 V

IOUT = 10 mA

Note 1

tON > 40 ns

Note 2

The value is configured by OTP and should not be modified while the buck is active.

Note 3

For short durations to meet peak current requirements, IOUT can be operated at up to 10 % higher than the

specified maximum operating condition. The part should not be operated in this mode for extended periods and is

not guaranteed for continuous operation.
