Description and Introduction

2A Wide Input Voltage Synchronous Buck-Boost DC/DC Converter The LTC3533EDE#TRPBF 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:

### **Manufacturer:**  
- **LINEAR** (Linear Technology, now part of Analog Devices)  

### **Part Number:**  
- **LTC3533EDE#TRPBF**  

### **Description:**  
- The **LTC3533** is a **dual-channel, synchronous buck-boost DC/DC converter** designed to provide regulated output voltages from input sources that may be above, below, or equal to the output voltage.  

### **Key Features:**  
1. **Wide Input Voltage Range:**  
   - **2.7V to 5.5V** (supports single Li-Ion, Li-Polymer, or multiple alkaline/NiMH cells).  

2. **Output Voltage Options:**  
   - **Adjustable output voltage** (via external resistors).  

3. **Buck-Boost Operation:**  
   - Seamlessly transitions between **buck and boost modes** for stable output.  

4. **Dual Independent Channels:**  
   - Two separate converters in a single package.  

5. **High Efficiency:**  
   - Up to **96% efficiency** (depending on load and conditions).  

6. **Synchronous Rectification:**  
   - Reduces power loss and improves efficiency.  

7. **Programmable Switching Frequency:**  
   - Adjustable from **300kHz to 2MHz** (allows optimization for efficiency or component size).  

8. **Low Quiescent Current:**  
   - **12µA per channel** in Burst Mode® operation (improves light-load efficiency).  

9. **Protection Features:**  
   - **Overcurrent protection (OCP), undervoltage lockout (UVLO), and thermal shutdown.**  

10. **Package:**  
   - **12-Lead DFN (3mm × 3mm)** (LTC3533EDE#TRPBF is the tape and reel version).  

### **Applications:**  
- **Portable battery-powered devices**  
- **USB-powered equipment**  
- **Handheld instruments**  
- **Dual-supply systems**  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official datasheet.
