Note 1: The MAX8627 is powered from OUTS. Once started, the IC operates down to 0.9V.
Note 2: Specifications to -40
°C are guaranteed by design and not production tested.
Note 3: The idle-mode current threshold is the transition point between fixed-frequency PWM operation and idle-mode operation.
The specification is given in terms of output load current for an inductor value of 1H. For a step-up converter, the idle-
mode transition varies with the input-to-output voltage ratio.
