Note 1: Operating voltage. Because the regulator is bootstrapped to the output, once started, the MAX1763 will operate down to
0.7V input. For conditions where V IN might exceed the set V OUT , or where V OUT is set above 4V, an external Schottky diode
must be connected from LX to POUT.
Note 2: Startup is tested with the circuit of Figure 2.
Note 3: Defines low-noise mode 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 from the 3.3V output is measured between the 3.3V output and 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. The gain block is
disabled.
Note 6: Connect AIN to OUT to disable gain block.
Note 7: ONA and ONB have hysteresis of approximately 0.15 ? V OUT .
Note 8: Specifications to -40°C are guaranteed by design and not production tested.
