Description and Introduction

Photoflash Capacitor Chargers with Output Voltage Monitor and Integrated IGBT Drive The LT3485EDD-0#TRPBF is a step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.4V to 16V  
- **Output Voltage Range:** Up to 40V  
- **Switching Frequency:** 1.2MHz  
- **Maximum Output Current:** 1A (dependent on input/output conditions)  
- **Package:** DFN-10 (3mm × 3mm)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Efficiency:** Up to 90%  
- **Features:**  
  - Adjustable output voltage  
  - Internal 2A, 40V switch  
  - Soft-start capability  
  - Current mode control  
  - Low shutdown current (<1μA)  
  - Thermal shutdown protection  

### **Descriptions and Features:**  
The LT3485EDD-0#TRPBF is a high-efficiency, monolithic step-up DC/DC converter designed for applications requiring high output voltages. It integrates a 2A, 40V power switch and operates at a fixed 1.2MHz switching frequency, allowing the use of small external components.  

Key features include adjustable output voltage via an external resistor divider, soft-start functionality to limit inrush current, and current mode control for stable operation. The device is available in a compact DFN-10 package, making it suitable for space-constrained applications.  

It is commonly used in automotive, industrial, and battery-powered systems requiring high-voltage generation from lower input sources.  

(Note: Always refer to the official datasheet for precise specifications and application details.)
