Note 2: The MAX1566/MAX1567 are powered from the step-up output (PVSU). An internal low-voltage startup oscillator drives the
step-up starting at approximately 0.9V until PVSU reaches approximately 2.5V. When PVSU reaches 2.5V, the main control
circuitry takes over. Once the step-up is up and running, it can maintain operation with very low input voltages; however,
output current is limited.
Note 3: Since the device is powered from PVSU, a Schottky rectifier, connected from the battery to PVSU, is required for low-voltage
startup.
Note 4: The step-up regulator is in startup mode until this voltage is reached. Do not apply full load current during startup. A power-
OK output can be used with an external PFET to gate the load until the step-up is in regulation. See the AUX1OK , SDOK ,
and SCF Connections section.
Note 5: The step-up current limit in startup refers to the LXSU switch current limit, not the output current limit.
Note 6: If the main converter is configured as a step-up (SUSD = PVSU), the P-channel synchronous rectifier is disabled until the
2.5V normal operation threshold has been exceeded. If the main converter is configured as a step-down (SUSD = GND), all
step-down operation is locked out until the normal operation threshold has been exceeded. When the main is configured as
a step-down, operation in dropout (100% duty cycle) can only be maintained for 100,000 OSC cycles before the output is
considered faulted, triggering global shutdown.
Note 7: Operation in dropout (100% duty cycle) can only be maintained for 100,000 OSC cycles before the output is considered
faulted, triggering global shutdown.
Note 8: ONM, ONSD, ON1, ON2, and ON3 are disabled until 1024 OSC cycles after PVSU reaches 2.7V.
