General Description
The MAX8569A/MAX8569B low-quiescent-current
boost regulators provide up to 200mA at output volt-
ages up to 5.5V from a 1.5V to 5.5V input source. The
built-in synchronous rectifier allows for over 90% effi-
ciency while achieving small size and low cost by elimi-
nating the need for an external Schottky diode.
The MAX8569A provides an adjustable output while the
MAX8569B is fixed at 3.0V or 3.3V. The MAX8569B fea-
tures a power-on reset output ( RST ) to signal that the
output has reached regulation. All devices connect the
battery input to the output during shutdown, allowing
the input battery to be used as a backup or real-time
clock supply when the converter is off.
