Description and Introduction

High Speed, Precision Delay RS485 Quad Line Receivers The LTC1519IS is a low-power, step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 100mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Quiescent Current:** 20µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring regulated output from low input voltages.  
- Uses a fixed-frequency PWM control scheme for low noise and stable operation.  
- Includes internal soft-start to limit inrush current.  
- Low shutdown current (<1µA) for power-saving modes.  
- Requires minimal external components (inductor, diode, capacitors).  
- Suitable for portable devices, handheld instruments, and backup power applications.  

For detailed electrical characteristics and application circuits, refer to the official datasheet.
