Pololu 7.5V, 15A Step-Down Voltage Regulator D24V150F7

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 40 V and efficiently reduces it to 7.5 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.

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)
• 7.5 V output 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 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: 1.7″ × 1.25″ × 0.43″ (43.2 mm × 31.8 mm × 11 mm)
• Four 0.086″ mounting holes for #2 or M2 screws
