An efficient step-down converter that reduces the input voltage to 12 V at a maximum current of 100 mA, offering high efficiency due to low quiescent current (<50 μA). It supports input voltage from 12 V to 65 V, has a Power Good (PGOOD) function, an EN input for system shutdown, and short circuit and overheat protection, making it a reliable and energy-efficient solution.

Description

The D45V1Ex module is a high-efficiency buck (step-down) voltage regulator that lowers the input voltage to 12 V with a maximum output current of 100 mA. It is a switching regulator (SMPS) characterized by an extremely low quiescent current (below 50 μA), ensuring high efficiency even under light loads. This makes it more energy-efficient than traditional linear regulators. The regulator supports an input voltage range of 12 V to 65 V, with the minimum voltage depending on the voltage drop at a given load. The device features a Power Good (PGOOD) function, which signals correct output voltage, and an EN input that allows the circuit to be disabled, entering a low-power mode (approximately 5 μA in sleep mode). Additionally, a low-voltage threshold can be set using an external resistor. The module is equipped with short-circuit and over-temperature protection, ensuring high reliability. Its compact size facilitates integration into various electronic projects.

Pinout Description

  • PGOOD - Open-drain output that goes low when the output voltage drops below 87% of the nominal value.
  • EN - The regulator is enabled by default. Setting the EN pin low turns off the power supply and puts the module into low-power mode.
  • VIN - Power input
  • GND - Ground
  • VOUT - Output
