SY75572LMG-TR

SY75572LMG-TR is a high‑efficiency DC-DC buck regulator from Silergy (SY). It integrates the switching MOSFETs and is designed to convert a higher input voltage down to a precise, lower output for digital ICs, processors, and power rails. The -TR suffix denotes Tape & Reel packaging; LMG indicates the specific package family.
Key points:
- Step-down regulator with externally set output via feedback resistors.
- Internal protection: overcurrent, thermal shutdown, undervoltage lockout.
- Features such as soft-start and enable control; switching frequency chosen to balance efficiency and component size.
- Wide applicability: CPU/GPU memory rails, FPGAs/SoCs, automotive and consumer electronics.
External parts required: input capacitor, output capacitor, inductor, feedback divider; possibly compensation network depending on the design.
For exact input range, achievable output voltages, current capability, pinout, and recommended application circuit, consult the official SY75572LMG-TR datasheet and reference designs.
