VIN = 3.6V, IOUT = 400mA

VOUT_ripple Ripple voltage, PWM mode

1. Ripple voltage should measured at COUT electrode on good layout PC board and under condition using suggested inductors and capac-

itors.

Note:

All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality

Control) methods.
