32L QFN .EPS
MAX1809
before startup, a 100Ω resistor should be added in the
feedback path, and a diode from FB to SS as shown in
Figure 10. SS will keep FB low during the startup
sequence, ensuring that the MAX1809 enters into PWM
mode and begins sinking current. See the Soft-Start
Sink Current specification in the Electrical
Characteristics for resistor selection.
