imum DC output current (10A or less). Note that some
fine-tuning may be required when selecting the current-
limit resistors. Errors are introduced as a result of the
MAX5069A IC current-limit propagation delays.
Input Undervoltage Lockout (UVLO)
The MAX5069A EV kit features a brownout and input-
supply startup UVLO circuit that prevents operation
below the programmed input-supply start voltage.
Resistors R5 and R6 set the input undervoltage lockout
threshold of the EV kit. To evaluate other input UVLO
voltages, replace resistor R5 with another surface-mount
resistor (0805 size). Using the desired startup voltage,
resistor R5 is then found by the following equation:
where VIN
STARTUP
is the desired startup voltage at which
the EV kit starts and resistor R6 is typically in the 20k
range. Refer to the
MAX5069A/D UVLO Adjustment
and
Bootstrap Undervoltage Lockout
sections of the
MAX5069 data sheet for additional information on the
UVLO/EN pin of the MAX5069A IC.
