Note 1:
Operating voltage. Because the regulator is bootstrapped to the output, once started, the MAX1763 will operate down to
0.7V input.
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

Note 8:
Specifications to -40
