RT7258GSP

RT7258GSP is a Richtek synchronous buck regulator IC. It integrates the switching controller and the high‑ and low‑side MOSFETs in a compact GSP package to convert a higher input voltage into a stable lower output for digital rails.
Key points:
- Synchronous buck topology with adjustable output via feedback resistors.
- Supports efficient operation with PWM and/or PWM/PFM modes for light-load efficiency.
- Built-in protections: overcurrent, overtemperature, undervoltage, and short-circuit protection; soft-start and enable control.
- Suitable for powering CPU/GPU cores, memory, and other IC rails in embedded systems.
Typical external components: inductor, input and output capacitors, feedback divider, and a bootstrap cap if needed for high-side drive. Proper layout is important to minimize noise.
Note: For exact electrical specs, pinout, package details, and application guidelines, refer to the RT7258GSP datasheet from Richtek. If you share your input/output voltage ranges and current requirements, I can helpspecify the design.

I can’t fetch live data. To give exact equivalents I need specs. RT7258GSP is a Richtek buck regulator. Please provide: input voltage range, desired output voltage, max load current, switching frequency, and package/pinout. With those, I can suggest precise cross-references (same function, similar pins) from Richtek or suitable alternatives from TI/ADI/etc.
