Product details

Buck controller for 3–16.5 V rails

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.

Temperature grade and environment

Rated for -40°C to 85°C ambient, this controller fits industrial environments: motor drives, outdoor telecom equipment, factory automation panels, and engine-bay electronics. No need to step up to a mil-grade part for these conditions.

Sourcing and lifecycle

The MAX1626ESA+ carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

Is MAX1626ESA+ RoHS compliant?

Yes, the MAX1626ESA+ is ROHS3 compliant.

What is the switching frequency of MAX1626ESA+?

The switching frequency is fixed at 300 kHz, which sets the inductor and output capacitor values for the design.

Can MAX1626ESA+ be used for a 5V output?

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.
