Description and Introduction

Switched Capacitor Voltage Converter The LM2767M5X is a switched capacitor voltage inverter manufactured by Texas Instruments (NS). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage:** -Vin (inverted input voltage)  
- **Output Current:** Up to 25mA  
- **Switching Frequency:** 450kHz (typical)  
- **Efficiency:** Up to 96%  
- **Quiescent Current:** 120µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The LM2767M5X is a high-efficiency, low-noise switched capacitor voltage inverter that generates a negative output voltage from a positive input supply. It is designed for applications requiring a small negative voltage rail with minimal external components.  

### **Features:**  
- **Low External Component Count:** Requires only two small capacitors.  
- **No Inductors Needed:** Uses a charge pump architecture.  
- **Low Noise:** Minimizes output ripple.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Space-Saving Package:** SOT-23-5 footprint.

Description and Introduction

Switched Capacitor Voltage Converter The LM2767M5X is a high-efficiency, fixed-frequency step-down DC-DC converter manufactured by National Semiconductor (NS国半). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** Fixed 1.8V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.6MHz (typical)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LM2767M5X is a synchronous step-down DC-DC converter optimized for battery-powered applications.  
- It integrates both high-side and low-side MOSFETs for improved efficiency.  
- The fixed-frequency PWM architecture ensures stable performance under varying load conditions.  

### **Features:**
- **High Efficiency:** Up to 96% due to synchronous rectification.  
- **Low Quiescent Current:** 16µA (typical) in shutdown mode.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Enhances reliability under fault conditions.  
- **Small Footprint:** SOT-23-5 package for space-constrained designs.
