Pololu 12V 15A Step-Down Spannungsregler Voltage Regulator D24V150F12

Pololu 12V 15A Step-Down Spannungsregler Voltage Regulator D24V150F12

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 40 V and efficiently reduces it to 12 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.

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 40 V and efficiently reduces it to 12 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.

These regulators have an instantaneous current limit of approximately 32 A, but they are limited in the long term to much lower currents by power dissipation and the corresponding temperature rise that induces in the board. The regulators can typically support continuous output currents between 5 A and 20 A without additional cooling (such as with a heat sink or forced airflow), depending on the input voltage and output voltage. In general, the available output current is a little higher for the lower-voltage versions than it is for the higher-voltage versions, and it decreases as the input voltage increases.

Features

Input voltage:
- 4.5 V to 40 V for the version that outputs 3.3 V
- [output voltage + dropout voltage] to 40 V for output voltages of 5 V and higher (see below for more information on dropout voltage)
Fixed 3.3 V, 5 V, 6 V, 7.5 V, 9 V, or 12 V output (depending on regulator version) with 4% accuracy
Typical maximum continuous output current between 5 A and 20 A
Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load
Integrated reverse-voltage protection, over-current and short-circuit protection, over-temperature shutoff, undervoltage lockout, and soft-start
Typical no-load quiescent current of 100 mA ; this can be reduced to approximately 5 µA to 10 µA per volt on VIN by disabling the board
“Power good” output indicates when the regulator cannot adequately maintain the output voltage
Compact size: 43.2 mm × 31.8 mm × 11 mm
Weight: 19 g
Four 0.086″ mounting holes for #2 or M2 screws

General specifications

Minimum operating voltage: 14.5 V, For small loads; this voltage rises approximately linearly up to around 15.2 V at 15 A output.
Maximum operating voltage: 40 V
Continuous output current: 15 A, 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.
Output voltage: 12 V
Reverse voltage protection?: Y
Maximum quiescent current: 100 mA, 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.
