Description and Introduction

Dual 2-Phase, No RSENSE Low VIN Synchronous Controller The LTC3836EUFD#PBF is a high-efficiency, dual-phase synchronous step-down DC/DC controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.6V to 5.5V (adjustable)  
- **Switching Frequency:** 200kHz to 2.2MHz (programmable)  
- **Maximum Output Current:** Up to 25A per phase (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 28-Lead QFN (5mm × 5mm)  

### **Descriptions:**  
- The LTC3836EUFD#PBF is a dual-phase, current-mode controller designed for high-current, low-voltage applications.  
- It uses a constant-frequency, current-mode architecture with programmable phase interleaving to reduce input and output ripple.  
- Features include adjustable soft-start, power-good indication, and differential remote sensing for accurate voltage regulation.  

### **Features:**  
- **Dual-Phase Operation:** Reduces input/output ripple and improves thermal performance.  
- **Programmable Frequency:** Allows optimization for efficiency and component size.  
- **Precision Reference:** ±1% output voltage accuracy over temperature.  
- **Current Mode Control:** Ensures fast transient response and stability.  
- **External Synchronization:** Can sync to an external clock.  
- **Foldback Current Limiting:** Protects against short circuits.  
- **Low Shutdown Current:** <1µA when disabled.  

This controller is commonly used in high-performance power supplies for telecom, industrial, and computing applications.
