5V, 5.5A Step-Down Voltage Regulator D36V50F5
This powerful synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 5 V. The board measures only 1″ × 1″ yet delivers typical maximum continuous output currents between 3.5 A and 8 A, depending on the input voltage, which makes it well suited for powering moderate to large loads. An optional enable input with a precise cutoff threshold can be used to put the regulator in a low-power state with a current draw of 10 µA to 20 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output that indicates when the regulator cannot adequately maintain the output voltage.

- Without included optional headers.
- Subject to dropout voltage considerations. See the dropout voltage graph under the description tab for more information.
- Typical continuous output current at 36 V in. 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.
- To -40 V. Connecting supplies over 40 V in reverse can damage the device.
- While enabled with no load. Can be reduced to under 1 mA using the enable pin.
