Description and Introduction

Improved Industry Standard Single Ended Current Mode PWM Controller The ISL6844IU is a high-frequency, dual MOSFET driver designed for synchronous buck converters. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Renesas Electronics (formerly Intersil)
- **Package:** 10-Lead QFN (Quad Flat No-Lead)
- **Input Voltage Range (VDD):** 4.5V to 5.5V  
- **Output Drive Current (Peak):** 4A (sink/source)  
- **Propagation Delay (Typical):** 30ns  
- **Rise/Fall Time (Typical):** 10ns (with 1.8nF load)  
- **Operating Frequency:** Up to 2MHz  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The ISL6844IU is a dual MOSFET driver optimized for high-efficiency synchronous buck converters.  
- It features independent high-side and low-side gate drivers with fast switching speeds.  
- The device includes adaptive dead-time control to prevent shoot-through in power MOSFETs.  

### **Features:**
- **Dual Output Drivers:** Independent high-side and low-side gate drivers.  
- **Adaptive Dead-Time Control:** Ensures no cross-conduction between MOSFETs.  
- **High-Speed Switching:** Fast propagation delays and rise/fall times for high-frequency operation.  
- **4A Peak Drive Current:** Capable of driving large MOSFETs efficiently.  
- **Wide Input Voltage Range:** Supports 4.5V to 5.5V logic-level inputs.  
- **Low Power Consumption:** Optimized for energy-efficient applications.

- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (Quad Flat No-Lead)  

### **Descriptions:**  
- The ISL6844IU is a dual-phase, synchronous buck PWM controller designed for high-efficiency DC/DC voltage regulation.  
- It provides precise voltage regulation for applications such as servers, telecom, and industrial power supplies.  
- The device supports adjustable switching frequency and phase-shifted operation to reduce input ripple current.  

### **Features:**  
- **Dual-Phase Operation:** Reduces input/output capacitor requirements.  
- **Adjustable Switching Frequency:** 300kHz to 1MHz for design flexibility.  
- **Precision Reference Voltage:** 0.6V ±1% accuracy.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Overcurrent Protection (OCP):** Uses MOSFET RDS(ON) sensing.  
- **Overvoltage Protection (OVP):** Monitors output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup.  
- **Synchronous Rectification:** Improves efficiency.  
- **Power-Good Indicator:** Monitors output status.
