Description and Introduction

White LED Driver with Integrated Schottky in 3mm x 2mm DFN The LT3591EDDB is a high-voltage, step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable from 0.8V to 29V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** DFN-8 (3mm x 3mm)  

### **Descriptions:**  
- The LT3591EDDB is a monolithic, step-down switching regulator with an integrated power switch.  
- It is designed for high-efficiency, compact power supply solutions.  
- Features include internal compensation, soft-start, and thermal shutdown.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4V to 30V input.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **High Switching Frequency:** 1MHz operation allows for small external components.  
- **Low Dropout Operation:** Maintains regulation with input voltages close to the output.  
- **Internal Power Switch:** Simplifies design by eliminating the need for an external MOSFET.  
- **Protection Features:** Includes thermal shutdown and current limiting.  

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

- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** DFN-8 (3mm × 3mm)  

### **Descriptions:**  
- The LT3591EDDB is a high-voltage, current-mode step-up DC/DC converter designed for driving LEDs or providing a regulated output voltage.  
- It includes an internal 40V, 100mA switch and features a constant-current or constant-voltage regulation mode.  
- The device operates in a fixed-frequency PWM mode for low noise and stable performance.  

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 2.5V to 15V.  
- **High Output Voltage Capability:** Can generate up to 40V.  
- **Integrated Power Switch:** Simplifies design with a built-in 100mA switch.  
- **Adjustable Output Current/Voltage:** Configurable via external resistors.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Small Footprint:** Available in a compact DFN-8 package.  

This information is based solely on the manufacturer's datasheet for the LT3591EDDB.
