Description and Introduction

Low IQ, Triple Output, Buck/Buck/Boost Synchronous Controller with Improved Burst Mode Operation The LTC3859AIFE#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 38V  
- **Output Voltage Range:** 0.8V to 5.5V  
- **Switching Frequency Range:** 50kHz to 900kHz (adjustable)  
- **Maximum Duty Cycle:** 98%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 38-Lead TSSOP (Exposed Pad)  
- **Topology:** Synchronous Buck Controller  
- **Control Method:** Current Mode  

### **Descriptions:**  
The LTC3859AIFE#PBF is a high-performance, dual-output synchronous step-down DC/DC controller designed for powering high-current, low-voltage loads. It features precision reference and current sensing for accurate regulation. The device supports PolyPhase® operation for reduced input ripple and improved thermal performance.  

### **Features:**  
- **Dual Outputs:** Can control two independent power stages.  
- **PolyPhase Operation:** Allows interleaving of multiple phases for reduced input/output ripple.  
- **Precision 0.8V Reference:** ±1% accuracy over temperature.  
- **Adjustable Frequency:** 50kHz to 900kHz.  
- **Differential Remote Sensing:** Ensures accurate output voltage regulation.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Power Good Output:** Monitors output voltage status.  
- **Wide Input Range:** Supports 4.5V to 38V operation.  
- **Low Shutdown Current:** <1µA.  

This device is commonly used in telecom, industrial, and computing applications requiring high-efficiency power conversion.
