概述

Description

RT9426WSC is a Richtek DC-DC buck regulator IC in a WSC package. It’s a synchronous buck converter (integrated high-side and low-side FETs) used to efficiently step down a higher input voltage to a lower, regulated output. Typical features include current-mode control, adjustable output via feedback, soft-start, enable/power-down, and protections such as UVLO, OVP, OCP, and thermal shutdown. The WSC suffix indicates a specific compact package/pinout. Common applications are point-of-load regulators for PMICs, CPUs/GPUs, embedded systems, and USB power modules. For exact electrical specs, pinout, and recommended external components, consult the official RT9426WSC datasheet.

Package

RT9426WSC comes in an 8-pin WSON package (WSON-8), typically 3.0 × 3.0 mm.

Pinout

- Pin count: 6 pins (SC-70 “WSC” package)
- Function: Buck regulator controller for DC-DC conversions (PWM switcher; provides reference, feedback, enable, oscillator to drive external MOSFETs).

Manufacturer

RT9426WSC is manufactured by Richtek Technology Corporation (Richtek). Richtek is a Taiwan-based fabless semiconductor company that designs and markets power management ICs, including DC-DC converters, PMICs, and LED driver ICs for consumer electronics, automotive, and industrial applications.

Application

RT9426WSC is a multi-channel synchronous buck controller for DC-DC power regulation. Typical applications include CPU/GPU core voltage regulation in notebooks and desktops, multi-rail VRMs for servers and telecom equipment, and other high-efficiency buck converters in consumer electronics.

Equivalent

I cannot provide exact equivalents without function/specs. RT9426WSC is a Richtek part; cross references depend on its role and ratings. Please specify: (1) function (DC-DC buck/charger/PD controller), (2) input/output voltage, (3) current rating, (4) package, (5) PD/USB-C features. I can then suggest concrete substitutes from TI, Analog Devices, ON Semiconductor, ST, Renesas, Microchip, etc., or you can use Digi-Key/Mouser cross-reference searches.
