Description and Introduction

No RSENSE Current Mode Synchronous Step-Down Switching Regulator The LTC1625IGN#TRPBF is a high efficiency, dual synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** 550kHz (programmable)  
- **Maximum Output Current:** Up to 20A (dependent on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP  

### **Descriptions:**  
- The LTC1625 is a dual synchronous buck controller designed for high efficiency power conversion.  
- It operates in constant-frequency current mode for precise regulation.  
- Features include soft-start, adjustable current limit, and independent tracking for each output.  

### **Features:**  
- **Dual Outputs:** Independent control of two step-down regulators.  
- **Synchronous Operation:** Reduces power loss by replacing Schottky diodes with MOSFETs.  
- **Programmable Frequency:** Allows optimization for efficiency and component size.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  
- **Current Mode Control:** Provides fast transient response and simplified loop compensation.  
- **Power Good Indicators:** Monitors output voltage status.  
- **Soft-Start:** Prevents inrush current at startup.  

This regulator is commonly used in distributed power systems, telecom/datacom equipment, and industrial applications.
