D45V5F3 - step-down inverter - 3,3V 0,5A - Pololu 5432
D45V5F3 is one of a series of miniature voltage regulators from Pololu , based on a synchronized step-down converter. It allows you to obtain an output voltage of 3.3 V from an input in the range of 4 V to 65 V. The maximum continuous output current depends on the input voltage and thermal conditions.

Product description: D45V5F3 - step-down converter - 3.3 V 0.5 A - Pololu 5432
D45V5F3 is one of the modules from the series of miniature voltage regulators from Pololu , based on a synchronized step-down converter . It allows to obtain an output voltage of 3.3 V from an input in the range of 4 V to 65 V. The maximum continuous output current depends on the input voltage and thermal conditions - it is typically 500 mA , and up to 700 mA . The module is characterized by high efficiency, low self-consumption (< 0.2 mA) and built-in protection against overheating and short circuit. Thanks to its miniature dimensions, it works great in tight design spaces.
D45V5F3 - step-down converter - 33V 0.5A - Pololu 5432.

Special Features
- Output voltage 3.3 V with ±4% accuracy - the module provides a stable voltage of 3.3 V, making it an ideal solution for systems requiring precise power supply, such as microcontrollers, sensors or communication modules
- Maximum output current up to 700 mA (typically 500 mA) - although the manufacturer declares a typical current output of 500 mA, the regulator is able to handle values up to 700 mA in appropriate conditions (cooling). This allows for powering more demanding loads without the risk of overload
- Wide input voltage range: from 4 V to 65 V - the regulator can work with high input voltages, making it a universal choice for industrial applications, battery power supplies or solar installations
- Switching frequency 1.1 MHz - high operating frequency ensures smaller passive components and fast system response. In case of low load, the regulator automatically reduces the frequency, increasing energy efficiency
- Built-in protection against short circuit and overheating - the module is equipped with mechanisms that protect both the controller itself and the connected devices against the effects of overloads, short circuits or excessive temperature rise
Converter terminals
- VOUT - output voltage 3.3 V
- GND - system ground (common for VIN and VOUT)
- VIN - input voltage from 4 V to 65 V
