Partnumber Manufacturer Quantity Availability
LTC3499EDD LT 2250 In Stock

Description and Introduction

750mA Synchronous Step-Up DC/DC Converters with Reverse-Battery Protection The LTC3499EDD is a synchronous step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 0.5V to 5V  
- **Output Voltage Range:** Up to 5.25V  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DFN-10 (3mm × 3mm)  

### **Descriptions:**  
The LTC3499EDD is designed for low-input-voltage applications, such as energy harvesting from solar cells or thermoelectric generators. It features a cold-start capability, allowing operation from input voltages as low as 0.5V. The device includes an internal synchronous rectifier for improved efficiency and a fixed-frequency PWM architecture for stable performance.  

### **Features:**  
- **Ultra-Low Start-Up Voltage:** Operates down to 0.5V  
- **Synchronous Rectification:** Improves efficiency  
- **Fixed 1MHz Switching Frequency:** Reduces external component size  
- **Automatic Burst Mode® Operation:** Enhances light-load efficiency  
- **Low Quiescent Current:** 25µA (typical)  
- **Integrated Soft-Start:** Prevents inrush current  
- **Thermal Shutdown Protection:** Safeguards against overheating

### **Descriptions:**  
The LTC3499EDD is a high-efficiency, synchronous step-up DC/DC converter designed for low-power applications. It operates from a single-cell Li-Ion battery or other low-voltage sources and provides a regulated output voltage.  

### **Features:**  
- **Ultra-Low Quiescent Current:** 20µA typical  
- **Wide Input Voltage Range:** 1.8V to 5.5V  
- **High Efficiency:** Up to 95%  
- **Synchronous Rectification:** Improves efficiency  
- **Adjustable Output Voltage:** Via external resistors  
- **Low Shutdown Current:** <1µA  
- **Small Footprint:** DFN package for space-constrained applications  
- **Fixed Frequency Operation:** 2.25MHz for minimal external components
