2D-048-015B-QFN32-C

Voltage Regulators - DC DC Switching Regulators Overview

The Helix Semiconductors 2D-048-015B-QFN32-C is a synchronous buck switching regulator IC featuring dual outputs of 24V and 12V. It operates within an input voltage range of 20V to 57V, delivering output currents of 650mA for the 24V rail and 1A for the 12V rail. The device utilizes a fixed switching frequency of 95kHz and is housed in a 32-VFQFN package with exposed pad. It supports surface mount mounting and functions across operating temperatures ranging from -40°C to +85°C or 0°C to +70°C depending on specific variant documentation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific operating temperature grade required for your application, as sources indicate both -40°C to +85°C and 0°C to +70°C ranges. Confirm the exact package dimensions against your PCB footprint design. Ensure compatibility with the 20V-57V input range before integration into existing power architectures.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated or non-isolated outputs are needed from a single wide-input source. Compare efficiency metrics against synchronous alternatives if thermal management is critical. Verify that the 95kHz switching frequency aligns with electromagnetic interference constraints in the target enclosure.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the Helix Semiconductors DC-DC converter lineup, specifically designed for power management tasks. It serves as a solution for converting higher bus voltages down to standard logic levels. The QFN32 form factor distinguishes it from larger through-hole regulators in similar product families.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes require matching dual-output capability and input voltage range. Check pin-to-pin compatibility with other 32-VFQFN buck regulators. Verify output current ratings meet or exceed 650mA and 1A requirements respectively.
