RT6160AWSC

Overview

The RT6160AWSC is a synchronous buck-boost DC-DC converter manufactured by Richtek USA Inc. It operates with an input voltage range of 2.2 V to 5.5 V and delivers up to 3 A output current. The device features a fixed switching frequency of 2.2 MHz and ultra-low quiescent current of 1 uA. It utilizes a 15-ball WLCSP package (1.4x2.3 mm) for compact surface-mount installation. The operating temperature range spans from -40°C to +85°C, supporting robust performance in portable electronics.

Feature Summary

Integrates an I2C interface for programmable output voltage, dynamic voltage scaling, and status monitoring.
Employs Advanced Constant On-Time control architecture for seamless transition between buck, boost, and buck-boost modes.
Supports automatic PFM mode and forced PWM mode selection to maintain high efficiency across load conditions.
Includes comprehensive protection mechanisms such as over-current, over-voltage, under-voltage lockout, and over-temperature protection.

Applications

Smartphones and tablets
Portable devices
Wearable devices
Wi-Fi modules
System pre-regulators

Procurement Notes

Verify the specific suffix AWSC against the manufacturer datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the 15-ball WLCSP footprint during PCB layout. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-inductor solution is needed for varying input voltages relative to the output rail. The I2C interface allows for system-level voltage adjustments without hardware changes. Consider the small WLCSP package size for space-constrained designs. Evaluate the 2.2 MHz switching frequency against EMI constraints and external component size requirements.

Part Context

This part belongs to the Richtek RT6160 family of high-efficiency buck-boost converters. It shares architectural similarities with other Richtek PMICs designed for mobile applications. The device is part of a broader portfolio including variants like the RT6158 and RT6166, differentiated by current ratings and package options.

Replacement Considerations

RT6166AP-A offers similar functionality with potentially different current capabilities or package variations. Verify electrical parameters and pin compatibility before substitution. Consult official cross-reference guides for confirmed alternatives.
