Description and Introduction

Dual 550kHz Synchronous 2-Phase Switching Regulator Controller with 5-Bit VID The LTC1703CG is a high-efficiency, synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 550kHz (fixed)  
- **Maximum Duty Cycle:** 100%  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Lead SSOP  

### **Descriptions and Features:**  
- **Synchronous Operation:** Uses external N-channel MOSFETs for high efficiency.  
- **Current Mode Control:** Provides fast transient response and stable operation.  
- **Low Dropout Operation:** Allows 100% duty cycle for low input-output differentials.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Short-Circuit Protection:** Includes cycle-by-cycle current limiting.  
- **Power Good Output:** Monitors output voltage status.  
- **Low Shutdown Current:** Typically 10µA when disabled.  

The LTC1703CG is designed for applications requiring high efficiency and compact power solutions, such as distributed power systems, industrial equipment, and portable devices.
