This synchronous switching step-down (or buck) regulator takes an input voltage of up to 40 V and efficiently reduces it to 3.3 V with an available output current of around 15 A. Typical efficiencies of 80% to 95% along with its high current capabilities make this regulator well suited for powering large loads. The regulator features reverse voltage protection and a power-good output that indicates when the regulator cannot adequately maintain the output voltage.

Maximum operating voltage: 40 V
Continuous output current: 15 A2
Output voltage: 3.3 V
Reverse voltage protection?: Y
Maximum quiescent current: 100 mA3

Identifying markings

PCB dev codes: reg18b
Other PCB markings: 0J9727

Notes:

1
Without included optional hardware.
2
This value is mainly for comparison to our other regulators. Actual achievable continuous output current is a function of input voltage and is limited by thermal dissipation. See the output current graph under the description tab for more information.
3
Typical maximum for the higher end of the input voltage range; it is a little lower at lower voltages. The ENABLE pin can be used to reduce the quiescent current to less than 10 μA per volt on VIN.
