Description and Introduction

Fast 2-Phase, No RSENSE Buck Controller with Output Tracking The LTC3708EUH#TR is a high-efficiency, dual-phase 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:** 0.8V to 5.5V (adjustable)  
- **Switching Frequency:** 50kHz to 850kHz (programmable)  
- **Maximum Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 32-Lead QFN (5mm x 5mm)  

### **Descriptions:**  
- The LTC3708EUH#TR is a dual-phase, synchronous step-down DC/DC controller optimized for high-current applications.  
- It uses a constant-frequency current-mode architecture for stable operation.  
- The dual-phase operation reduces input and output ripple current, improving thermal performance.  
- Features include adjustable soft-start, power-good indicator, and external synchronization capability.  

### **Features:**  
- Dual-phase operation for reduced input/output ripple  
- Programmable switching frequency (50kHz to 850kHz)  
- Adjustable output voltage (0.8V to 5.5V)  
- High efficiency (up to 95%)  
- Current-mode control for fast transient response  
- External synchronization capability  
- Adjustable soft-start  
- Power-good indicator  
- Overcurrent and overtemperature protection  
- Operates from a 4V to 36V input range  

This information is based on the manufacturer's datasheet and technical documentation.
