概述
Description
RT9164AGG is a RichTek voltage regulator IC (part of the RT9164 family). It’s a compact power-management device used to generate stable supply rails for portable/digital electronics.
Key points:
- Purpose: voltage regulation (fixed or adjustable outputs) in a small package.
- Features (typical): low quiescent current, solid line/load regulation, fast transient response, enable/soft-start, and protection options (overcurrent/overtemperature/UVLO).
- Packaging: AGG denotes a specific compact package style from RichTek.
- Applications: powering CPUs/microcontrollers, memory, sensors, and other digital ICs in battery-powered devices.
Note: exact specifications (input/output ranges, efficiency, pinout) vary by variant. Check the RT9164AGG datasheet for precise electrical characteristics and application guidance.

Equivalent
Exact equivalents depend on the RT9164AGG’s function and specs (input range, output, current, switching frequency, package). Please share Vin, Vout, Iout, freq, and package for precise cross-ref. In general, look at buck-regulator families from TI (TPS series), Analog Devices (ADP/ADP230x), Microchip (MCP/MIC series), and On Semiconductor (NCP series) for potential substitutes.
Features
RT9164AGG features (highlights):
- RichTek 8-pin synchronous buck regulator (integrated high- and low-side FETs) for high efficiency.
- Input range suitable for standard 2.5–5.5V rails.
- Adjustable output via feedback resistors (Vout range set by external network).
- PWM/PFM mode for good efficiency across light and heavy loads.
- Enable/Shutdown control and soft-start to limit inrush.
- Protections: overcurrent/short-circuit protection, thermal shutdown, UVLO.
- Internal reference and compensation suitable for compact external components.
- Small package options (8-pin SOP/DFN) with exposed pad for thermal dissipation.
Note: For exact electrical specs (Vout range, switching frequency, max load current, quiescent current), consult the RT9164AGG datasheet.
