Description and Introduction

Low IQ, Dual 2-Phase Synchronous Step-Down Controller The LTC3858EGN-1#PBF is a synchronous step-down DC/DC controller manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.6V to 5.5V  
- **Switching Frequency:** 50kHz to 900kHz (adjustable)  
- **Maximum Output Current:** Configurable with external components  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 24-Lead SSOP  

### **Descriptions:**
- The LTC3858EGN-1#PBF is a high-efficiency, synchronous step-down switching regulator controller.  
- It is designed for applications requiring high power density and efficiency.  
- The device features a constant-frequency current-mode architecture for stable operation.  
- It supports PolyPhase® operation for multi-phase power supply designs.  

### **Features:**
- **Wide Input Voltage Range:** Supports 4.5V to 38V operation.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Precision Reference:** 0.6V ±1% voltage reference for accurate regulation.  
- **Current Mode Control:** Ensures fast transient response and stability.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Differential Remote Sensing:** Improves output voltage accuracy.  
- **Phase-Lockable Frequency:** Synchronizable to an external clock.  
- **Low Shutdown Current:** <1µA when disabled.
