Note 1: Operating voltage—since the regulator is bootstrapped to the output, once started, the MAX1760 operates down
to 0.7V input.
Note 2: Startup is tested with the circuit shown in Figure 6.
Note 3: Defines maximum step-up ratio.
Note 4: The regulator is in startup mode until this voltage is reached. Do not apply full load current until the output exceeds 2.3V.
Note 5: Supply current into the OUT pin. This current correlates directly to the actual battery-supply current, but is reduced in
value according to the step-up ratio and efficiency.
Note 6: ON (MAX1760) and ON (MAX1760H) have a hysteresis of approximately 0.15 × V OUT .
Note 7: Specifications to -40°C are guaranteed by design and not production tested.
