Description and Introduction

High Speed, Precision Delay RS485 Quad Line Receivers The LTC1518IS is a product from Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)
- **Part Number:** LTC1518IS
- **Type:** Switched Capacitor Voltage Converter
- **Package:** SOIC (Small Outline Integrated Circuit)
- **Operating Temperature Range:** -40°C to +85°C
- **Input Voltage Range:** 1.5V to 5.5V
- **Output Voltage Options:** Adjustable or fixed (depending on configuration)
- **Output Current:** Up to 100mA (typical)
- **Efficiency:** Up to 90% (depending on load and input/output conditions)
- **Switching Frequency:** ~300kHz (typical)
- **Quiescent Current:** Low (typically in the microamp range for power-saving modes)

### **Descriptions:**
The LTC1518IS is a switched-capacitor voltage converter designed to provide regulated output voltages from a single input supply. It is commonly used in battery-powered applications where efficient power conversion is required. The device can operate in both step-up (boost) and step-down (inverting) configurations, making it versatile for various power supply needs.

### **Features:**
- **Wide Input Voltage Range (1.5V to 5.5V):** Suitable for battery-powered applications.
- **Low Quiescent Current:** Enhances efficiency in power-sensitive designs.
- **No Inductors Required:** Uses only external capacitors, simplifying PCB design.
- **Adjustable Output Voltage:** Can be configured for different output levels.
- **Low Noise Operation:** Minimizes interference in sensitive circuits.
- **Thermal Shutdown Protection:** Prevents damage from overheating.
- **Short-Circuit Protection:** Enhances reliability in fault conditions.

This information is based on the manufacturer's datasheet and technical documentation. For detailed application notes or circuit examples, refer to the official datasheet from Analog Devices (formerly Linear Technology).

Description and Introduction

High Speed, Precision Delay RS485 Quad Line Receivers The LTC1518IS 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 4.5V  
- **Output Voltage:** Adjustable (up to 5V)  
- **Output Current:** Up to 150mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 85%  
- **Quiescent Current:** 100µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
The LTC1518IS is designed for battery-powered applications requiring a regulated output voltage higher than the input supply. It features a low quiescent current, making it suitable for portable devices.  

### **Features:**  
- Low quiescent current (100µA)  
- Adjustable output voltage  
- Internal power switch (no external MOSFET required)  
- Soft-start for controlled inrush current  
- Shutdown mode (<1µA)  
- Short-circuit protection  
- Thermal shutdown  

This device is commonly used in battery-powered systems, PDAs, and portable instruments.
