Description

The D42V55F3 voltage regulator is a high-performance synchronous buck (step-down) converter designed to step down input voltages of up to 60 V to a stable 3.3 V. It features low no-load current consumption (<0.2 mA), making it energy-efficient even in standby mode. Its compact size allows installation in space-constrained environments. The D42V55F3 is an ideal solution for microprocessor systems, IoT devices, automation, and hobby projects where stable 3.3 V power with high efficiency and safe operation is required.

Thanks to switching technology (SMPS, DC-DC), the converter offers significantly higher efficiency (up to 95%) compared to traditional linear regulators, minimizing energy loss and heat generation. This model can deliver a continuous output current of up to 8 A at low input voltages, providing stable power even for demanding circuits. The unit includes reverse voltage protection, overcurrent protection, and thermal shutdown, ensuring high reliability in harsh operating conditions. The soft-start function limits inrush current and smoothly ramps up the voltage at startup, protecting connected devices.

The D42V55F3 converter features a set of pins for flexible integration into a power system. VOUT provides the regulated 3.3 V output, while GND serves as the common ground reference. VIN is used to supply the input voltage in the range of 3.5 V – 60 V, with the minimum operating voltage depending on the output voltage and dropout. The VRP pin outputs the input voltage after reverse voltage protection — it can serve as an output for powering other devices or as an alternative input bypassing this protection. Additionally, there is a PG (Power Good) pin — an open-drain output indicating proper output voltage — and an EN pin, which allows enabling or disabling the converter, including in low-power mode.
