Pololu 9V, 2.3A Step-Down Voltage Regulator D24V22F9
Converts up to 36V to stable 9V output
Ensures 85%-95% efficiency
Supports 2.3A continuous output
Includes integrated protections
Features compact design at 0.7″ × 0.7″ × 0.31″
The Pololu 9V, 2.3A Step-Down Voltage Regulator D24V22F9 efficiently converts higher input voltages, up to 36V, to a stable 9V output. This synchronous switching regulator offers typical efficiencies between 85% and 95%, making it more efficient than linear regulators, especially with large input-output voltage differences. It supports a continuous output current of up to 2.3A and features integrated protections against reverse voltage, over-current, short-circuit, and overheating. The regulator also includes a soft-start feature to minimize inrush current and a 'power good' signal to indicate output stability.
