Description and Introduction

Combination Battery Charger and DC/DC Converter The LTC1980EGN is a charge pump DC/DC converter manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- Linear Technology (LT)  

### **Part Number:**  
- LTC1980EGN  

### **Description:**  
- The LTC1980EGN is a switched-capacitor voltage inverter designed to generate a negative output voltage from a positive input supply. It operates with high efficiency and requires minimal external components.  

### **Key Features:**  
- **Input Voltage Range:** 1.5V to 5.5V  
- **Output Voltage:** -Vin (inverts input voltage)  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** 200kHz (typical)  
- **Low Quiescent Current:** 100µA (typical)  
- **Shutdown Mode:** <1µA (typical)  
- **No Inductors Required:** Uses only external capacitors  
- **High Efficiency:** Up to 96%  
- **Thermal Shutdown Protection**  
- **Package:** 8-Lead SSOP  

### **Applications:**  
- Negative voltage generation for analog circuits  
- Portable/battery-powered devices  
- LCD bias supplies  
- Data acquisition systems  

This information is based solely on the manufacturer's datasheet and technical documentation.

Description and Introduction

Combination Battery Charger and DC/DC Converter The LTC1980EGN is a charge pump DC/DC converter manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage:** Adjustable (positive or negative)  
- **Output Current:** Up to 20mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP (Narrow)  

### **Descriptions:**  
- The LTC1980EGN is a high-efficiency, switched-capacitor voltage inverter or doubler.  
- It can generate a regulated negative or positive output voltage from a single input supply.  
- The device operates in a charge pump topology, eliminating the need for inductors.  
- It includes an internal oscillator and requires minimal external components.  

### **Features:**  
- **Low Noise:** Uses frequency spread spectrum to reduce EMI.  
- **Low Quiescent Current:** Typically 350µA.  
- **Automatic Shutdown:** Reduces power consumption when not in use.  
- **Soft-Start:** Limits inrush current during startup.  
- **Short-Circuit Protection:** Built-in safeguards against output faults.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
