Description and Introduction

Synchronizing Current Mode PWM for Subscriber Line Interface Circuits (SLICs) The ISL6401CBZ-T is a step-down DC/DC converter manufactured by Intersil (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 14V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**
- The ISL6401CBZ-T is a synchronous buck (step-down) PWM regulator designed for high-efficiency power conversion.  
- It integrates both high-side and low-side MOSFET drivers, reducing external component count.  
- Features include overcurrent protection, thermal shutdown, and soft-start functionality.  

### **Features:**
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Soft-Start:** Limits inrush current during startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load currents.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  
- **Wide Input Voltage Range:** Suitable for various applications.  

This device is commonly used in telecom, networking, and industrial power supply applications.  

(Note: Intersil was acquired by Renesas Electronics in 2017.)

Description and Introduction

Synchronizing Current Mode PWM for Subscriber Line Interface Circuits (SLICs) The ISL6401CBZ-T is a synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** 300kHz (fixed)  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead DFN (3x3mm)  

### **Descriptions:**  
- The ISL6401CBZ-T is a high-performance, synchronous buck PWM controller designed for DC-DC voltage regulation.  
- It features voltage-mode control with an integrated error amplifier and supports high-efficiency power conversion.  
- The device includes overcurrent protection (OCP), undervoltage lockout (UVLO), and thermal shutdown for reliability.  

### **Features:**  
- **Voltage-Mode Control:** Ensures stable output regulation.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Adjustable Soft-Start:** Limits inrush current during startup.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  
- **Overcurrent Protection (OCP):** Prevents damage during fault conditions.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Thermal Shutdown:** Protects against overheating.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
