Description and Introduction

Dual, 550kHz, 2-Phase Synchronous Regulators The LTC3728LEGN#PBF is a synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** Up to 600kHz  
- **Topology:** Synchronous Buck Controller  
- **Duty Cycle:** Up to 100%  
- **Package:** 16-Lead SSOP  
- **Operating Temperature Range:** -40°C to 85°C  
- **Features:**  
  - Adjustable current limit  
  - Programmable soft-start  
  - Power-good output  
  - Low shutdown current (<1µA)  
  - Phase-lockable oscillator  

### **Description:**  
The LTC3728LEGN#PBF is a high-performance, dual-phase synchronous step-down switching regulator controller designed for high-efficiency power conversion. It drives external N-channel MOSFETs and supports multi-phase operation for reduced input/output ripple and improved thermal performance.  

### **Features:**  
- Dual-phase operation for reduced input/output capacitance  
- Adaptive anti-shoot-through protection  
- Programmable current limit with foldback  
- Adjustable switching frequency (up to 600kHz)  
- External synchronization capability  
- Low quiescent current in shutdown mode  

This device is commonly used in high-current applications such as servers, telecom, and industrial power systems.  

(Note: Always refer to the official datasheet for the most accurate and detailed information.)
