Description and Introduction

Constant Frequency Current Mode Flyback DC/DC Controller in ThinSOT The LTC3803ES6#PBF is a switching regulator controller manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)  
- **Package:** SOT-23-6  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable (via external components)  
- **Switching Frequency:** Up to 1MHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Duty Cycle Range:** 0% to 100%  
- **Current Limit:** Adjustable  
- **Quiescent Current:** ~100µA (typical)  

### **Descriptions:**
The LTC3803ES6#PBF is a high-efficiency, low-quiescent current step-down (buck) switching regulator controller. It is designed for applications requiring high efficiency and low power dissipation. The device operates over a wide input voltage range and can be configured for various output voltages using external components.  

### **Features:**
- **Wide Input Voltage Range (4V to 30V)** – Suitable for various power supply applications.  
- **High Efficiency** – Minimizes power loss with synchronous rectification capability.  
- **Adjustable Switching Frequency (Up to 1MHz)** – Allows optimization for efficiency and component size.  
- **Low Quiescent Current (~100µA)** – Improves efficiency in light-load conditions.  
- **Adjustable Current Limit** – Provides protection against overcurrent conditions.  
- **100% Duty Cycle Operation** – Ensures regulation even with low input voltages.  
- **Thermal Shutdown Protection** – Prevents damage from excessive heat.  
- **SOT-23-6 Package** – Compact footprint for space-constrained applications.  

This information is strictly based on the manufacturer's datasheet and specifications.
