Description and Introduction

200mA Buck-Boost Synchronous DC/DC Converters The LTC3531EDD#PBF is a product from **Linear Technology** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Manufacturer:** Linear Technology  
- **Part Number:** LTC3531EDD#PBF  
- **Type:** Buck-Boost DC/DC Converter  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.25V  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1.5MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DFN-8 (3mm × 3mm)  

### **Descriptions:**  
- The LTC3531EDD#PBF is a **synchronous buck-boost DC/DC converter** that provides a regulated output voltage from input voltages above, below, or equal to the output voltage.  
- It is designed for **low-power applications** and features automatic transitions between buck, buck-boost, and boost modes.  
- The device includes **internal power switches**, minimizing external component count.  

### **Features:**  
- **Seamless Transition:** Automatically switches between buck and boost modes for stable output.  
- **Low Quiescent Current:** 20μA (typical) in Burst Mode operation.  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Small Footprint:** DFN-8 package (3mm × 3mm) for space-constrained applications.  
- **Soft-Start & Short-Circuit Protection:** Ensures controlled startup and fault protection.  
- **Low Noise Operation:** Fixed-frequency PWM mode minimizes output ripple.  

This information is strictly based on manufacturer datasheets and technical documentation.
