Description and Introduction

Microprocessor CORE Voltage Regulator Precision Multi-Phase BUCK PWM Controller for Mobile Applications The ISL6219ACA is a power management IC manufactured by Intersil (now part of Renesas Electronics). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Intersil (NS - National Semiconductor, acquired by Intersil, now part of Renesas Electronics)  
- **Part Number:** ISL6219ACA  
- **Type:** Dual PWM Controller  
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** Adjustable (depends on external components)  
- **Switching Frequency:** Adjustable (typically 200kHz to 1MHz)  
- **Number of Outputs:** 2 (Dual PWM Controller)  
- **Duty Cycle:** Up to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead SSOP (Shrink Small Outline Package)  

### **Descriptions:**
The ISL6219ACA is a high-performance dual synchronous buck PWM controller designed for powering high-current, low-voltage processors and other DC-DC applications. It provides precise voltage regulation, efficiency optimization, and protection features.  

### **Features:**
- **Dual PWM Controller:** Supports two independent synchronous buck converters.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **High Efficiency:** Uses synchronous rectification for improved efficiency.  
- **Programmable Switching Frequency:** Allows optimization for performance and noise.  
- **Overcurrent Protection (OCP):** Monitors and protects against excessive current.  
- **Overvoltage Protection (OVP):** Safeguards against voltage spikes.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Power-Good Output:** Provides a signal indicating stable output voltage.  
- **Soft-Start Function:** Prevents inrush current during startup.  

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