Description and Introduction

WLL & ISDN-TA SUBSCRIBER LINE INTERFACE CIRCUIT The STLC3055N is a power management IC manufactured by STMicroelectronics (STM). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics (STM)  
- **Type:** Power Management IC  
- **Package:** SO-8 (Small Outline 8-pin)  
- **Operating Voltage Range:** Typically 4.5V to 36V  
- **Output Current:** Up to 3A (depending on configuration)  
- **Switching Frequency:** Adjustable (typically up to 500kHz)  
- **Efficiency:** High efficiency (typically >90%)  
- **Protection Features:** Overcurrent, overtemperature, and undervoltage lockout (UVLO)  

### **Descriptions:**  
The STLC3055N is a step-down (buck) DC-DC converter designed for high-efficiency power conversion in various applications. It integrates a power MOSFET and control circuitry to provide a compact solution for voltage regulation.  

### **Features:**  
- **Integrated Power MOSFET** for reduced external component count  
- **Adjustable Output Voltage** via external resistors  
- **Wide Input Voltage Range** (4.5V to 36V)  
- **High Efficiency** with synchronous rectification  
- **Thermal Shutdown Protection** for safe operation  
- **Soft-Start Function** to limit inrush current  
- **Low Quiescent Current** in standby mode  

This information is based on the manufacturer's datasheet and technical documentation. For exact performance characteristics, refer to the official STMicroelectronics datasheet.

Application Scenarios & Design Considerations

WLL & ISDN-TA SUBSCRIBER LINE INTERFACE CIRCUIT

Alternative Part Number

  • LE58QL021BVC --: Integrated subscriber line interface circuit (SLIC) with similar telecom line-interface function; widely used as a cross-reference for ST SLIC devices.
  • HC55185ECM --: Telecom SLIC offering comparable battery-feed and line supervision features, suitable as a functional substitute in voice-line applications.
  • BCM6301 --: Subscriber line interface device used in telecom access equipment; can serve as an alternative when the STLC3055N is unavailable, subject to design verification.
  • LE58QL021VC --: Subscriber line interface circuit (SLIC) in the same telecom voice-line function class; widely used as a second-source SLIC for STLC3055N designs.
  • HC55185ECB --: Telecom SLIC with comparable battery-feed and supervision features, commonly cross-referenced for ST SLIC parts.
