The IC is powered from the OUTSU output.
Since the part is powered from OUTSU, a Schottky rectifier, connected from the input battery to OUTSU, is required for
low-voltage startup.
The step-up regulator operates in startup mode until this voltage is reached. Do not apply full load current during startup.
The step-up current limit in startup refers to the LXSU switch current limit, not an output current limit.
The idle-mode current threshold is the transition point between fixed-frequency PWM operation and idle-mode operation
(where switching rate varies with load). The spec is given in terms of inductor current. In terms of output current, the idle-
mode transition varies with input/output voltage ratio and inductor value. For the step-up, the transition output current is
approximately 1/3 the inductor current when stepping from 2V to 3.3V. For the step-down, the transition current in terms of
output current is approximately 3/4 the inductor current when stepping down from 3.3V to 1.8V.
