800mA, Low-Noise, Step-Up DC-DC Converter
with 500mA Linear Regulator
Note 1: Operating voltage. Since the regulator is bootstrapped to the output, once started it will operate down to 0.7V input.
Note 2: The device is in startup mode when V
Note 3: Supply current into the OUT and POUT pins. This current correlates directly to the actual battery-supply current, but is
Note 4: Minimum recommended ISET voltage in normal mode is 0.625V.
Note 5: ONA, ONB, ONL have hysteresis of approximately 0.15
Note 6: Specifications to -40°C are guaranteed by design and not production tested.
