The Enable pin provides a simple on/off control for power sequencing or low-power standby. With no synchronous rectifier, the external diode handles the low-side path, which is a cost-effective choice for output currents up to a few amps depending on the external MOSFET and inductor selected.
No need to step up to a mil-grade part for these conditions.
Yes, the MAX1626ESA+ is ROHS3 compliant.
The switching frequency is fixed at 300 kHz, which sets the inductor and output capacitor values for the design.
Yes, with a supply voltage between 3 V and 16.5 V, the controller can regulate a 5 V output by selecting the appropriate external MOSFET, inductor, and feedback resistors.
