wise noted.) (Note 8)
Note 1: Operating voltage. Because the regulator is bootstrapped to the output, once started, the MAX1763 will operate down to
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
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°C are guaranteed by design and not production tested.
