Auxiliary LDO Feedback Input. Connect a resistive voltage-divider from OUTA to analog ground to adjust
the auxiliary linear-regulator output voltage. FBA regulates at 1V.
Adjustable Auxiliary Linear-Regulator Output. Bypass OUTA to GND with 1µF or greater capacitor
(1µF/25mA). When DRVA < OUTA, the secondary feedback control triggers the DL5 for 1µs forcing the
controller to recharge the auxiliary storage capacitor. When DRVA exceeds 25V, the MAX17003/MAX17004
enable a 10mA shunt on OUTA, preventing the storage capacitor from rising to unsafe levels due to the
transformer’s leakage inductance. Pulling ONA high enables the linear-regulator driver and the secondary
feedback control.
Exposed Pad. Connect the exposed backside pad to analog ground.
