Key Features
- 4 MHz switching frequency enables use of miniature external inductors and capacitors, reducing total solution size on space-constrained PCBs
- 50 V input voltage rating supports direct connection to automotive 12 V/24 V rails and industrial 48 V bus voltages with substantial margin
- 1 A output current with integrated synchronous rectification delivers high efficiency across light and heavy load conditions without an external catch diode
Applications
The MP2562DQ-LF-P is used in automotive, industrial, and telecommunications applications requiring efficient step-down voltage conversion from high-voltage rails above 24 V down to logic supply levels of 3.3 V or 5 V. Its 4 MHz switching frequency minimizes external passive component sizes, supporting compact power supply designs on modules where board space is limited. The 50 V input rating suits it for direct connection to automotive 12 V start-stop systems and 48 V mild-hybrid rails.

Frequently Asked Questions
What input voltage range can the MP2562DQ-LF-P handle, and is it suitable for 48 V industrial bus applications?
The MP2562DQ-LF-P supports an input voltage up to 50 V, making it directly compatible with 48 V industrial bus systems and automotive 12 V/24 V rails with headroom to absorb load-dump transients. It can step down from a 48 V bus to a regulated 5 V or 3.3 V output at up to 1 A output current without an external boost stage or voltage clamping circuitry.
How does the 4 MHz switching frequency of MP2562DQ-LF-P enable a smaller PCB footprint compared to lower-frequency converters?
At 4 MHz switching frequency, the required inductor value for a 1 A output typically drops to around 2.2 µH to 4.7 µH versus 22 µH to 47 µH at 500 kHz. Smaller inductance values mean physically smaller and lighter inductors with lower DCR, while output capacitance can be reduced to 10 µF or less. This allows the complete power stage to fit within a footprint under 50 mm², which is significantly smaller than equivalent 400 kHz converter solutions.
What is the maximum output current of MP2562DQ-LF-P and how does it compare to higher-current alternatives in the MPS portfolio?
The MP2562DQ-LF-P delivers a maximum output current of 1 A, which is adequate for powering microcontrollers, FPGAs at lower logic voltages, and sensor subsystems drawing under 800 mA continuously. For applications requiring 2 A or 3 A from similar 50 V-rated MPS step-down converters, the MP2563 or MP2564 series offer higher current ratings in comparable package sizes with the same 4 MHz high-frequency architecture.
