Description and Introduction

Precision Multi-Phase Buck PWM Precision Multi-Phase Buck PWM Positioning IMVP-IV? and IMVP-IV The ISL6217CVZ-T is a synchronous buck PWM controller manufactured by Intersil (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Intersil (now Renesas Electronics)  
- **Part Number:** ISL6217CVZ-T  
- **Package:** 16-Lead QSOP  
- **Input Voltage Range:** 5V to 24V  
- **Output Voltage Range:** Adjustable (typically 0.9V to 5.5V)  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Output Current:** Supports high-current applications (external MOSFETs required)  
- **Efficiency:** High efficiency due to synchronous rectification  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The ISL6217CVZ-T is a high-performance, dual-phase synchronous buck PWM controller designed for powering high-current processors and other DC-DC conversion applications. It integrates control, monitoring, and protection features to ensure stable and efficient power delivery. The device supports adjustable output voltage and switching frequency, making it suitable for various power supply designs.  

### **Features:**  
- **Dual-Phase Operation:** Reduces input ripple current and output voltage ripple.  
- **Adjustable Switching Frequency:** 300kHz to 1MHz for flexibility in design.  
- **Voltage Positioning (Droop Control):** Improves transient response.  
- **Precise Output Voltage Regulation:** ±1% accuracy over line, load, and temperature.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent Protection (OCP):** Monitors and protects against excessive current.  
- **Overvoltage Protection (OVP):** Safeguards the load from voltage spikes.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Power-Good (PG) Output:** Indicates when the output is within regulation.  
- **Thermal Shutdown:** Protects the device from overheating.  

This information is strictly factual and derived from the manufacturer's datasheet and technical documentation.
