Overview

Description

RT9053AZQW is a Richtek Technology DC-DC buck regulator (RT9053 family) in an 8-pin WQFN/SOP‑style package. It’s used to generate a stable lower voltage rail from a higher input in battery-powered devices (phones, wearables, cameras, etc.). Key ideas: integrated switching MOSFETs and regulator circuitry, enable control, and protection features (overcurrent/overtemperature). Output voltage can be fixed or adjustable via a feedback network, with typically high efficiency for compact power boards. Exact electrical specs (input range, switching frequency, available output voltages) vary by variant; consult the RT9053AZQW datasheet for precise details and pinout.

Features

RT9053AZQW is a Richtek regulator. Key features (typical for RT9053 family; exact values depend on the variant) include:
- Single-channel regulator in an 8-pin AZQW package
- Low quiescent current with good line/load regulation
- Low dropout behavior for efficient operation
- Enable/shutdown control pin
- Overcurrent/short-circuit protection and thermal shutdown
- Soft-start to prevent inrush
- Suitable for fixed-output or adjustable-output configurations (exact option depends on part variant)
- Compatible with ceramic capacitors and compact PCB layouts
Note: For precise electrical specs (input range, fixed vs. adjustable outputs, current capability, dropout, and exact protection features), consult the current datasheet for RT9053AZQW and the exact sub-variant you’re using.

Package

QFN-16 package, typically 4×4 mm (with wettable flank).

Pinout

8 pins (QFN-8 package). It is a lightweight step-down DC-DC buck regulator with an enable input; used to regulate a higher input voltage down to a stable output voltage for portable devices.

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek).
- Company type: Taiwan-based semiconductor company that designs and manufactures analog/mixed-signal integrated circuits, especially power management ICs (PMICs), such as DC-DC converters, battery chargers, and LED drivers.

Application

RT9053AZQW is a power management IC (DC-DC regulator). Typical application areas:
- Portable devices (smartphones, tablets, wearables) for core and I/O rail generation
- Embedded systems and IoT sensors needing efficient voltage conversion
- USB-powered peripherals and charging circuits
- Compact power rails in consumer electronics and small industrial/automotive electronics
