7.5V, 2.4A Step-Down Voltage Regulator D24V22F7 Pololu 2860

7.5V, 2.4A Step-Down Voltage Regulator D24V22F7 Pololu 2860

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 7.5 V. The board measures only 0.7″ × 0.7″ yet delivers a typical continuous output current of up to 2.4 A and features reverse voltage protection. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors. An optional shutdown pin enables a low-power state with a current draw of around 30 μA to 350 μA, depending on the input voltage, and a power-good output indicates when the regulator cannot adequately maintain the output voltage.

• Input voltage:
  • 4 V to 36 V for the version that outputs 3.3 V
  • [output voltage + dropout voltage] to 36 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: >2 A
• Typical efficiency of 85% to 95%, depending on input voltage, output voltage, and load
• Switching frequency: ~400 kHz
• Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, and soft-start
• 1 mA typical no-load quiescent current; 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: 0.7″ × 0.7″ × 0.31″ (17.8 mm × 17.8 mm × 8 mm)
• Two 0.086″ mounting holes for #2 or M2 screws
