Description and Introduction

Triple Output/ Low-Noise LDO Regulator with Integrated Reset Circuit The ISL6411IR is a high-performance, dual-output power supply controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage 1 (VOUT1):** Adjustable from 0.8V to 3.3V  
- **Output Voltage 2 (VOUT2):** Adjustable from 1.25V to 5.5V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Output Current:** Up to 6A (combined)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (4mm x 4mm)  

### **Descriptions:**
- The ISL6411IR is a dual-output synchronous buck controller designed for high-efficiency power conversion.  
- It integrates two PWM controllers to regulate two independent output voltages.  
- Supports adjustable switching frequency for optimization of efficiency and component size.  
- Features voltage tracking and sequencing capabilities for complex power-up/down requirements.  

### **Features:**
- **Dual Independent PWM Controllers** for flexible power management.  
- **Adjustable Output Voltages** via external resistors.  
- **Programmable Soft-Start** for controlled power-up sequencing.  
- **Overcurrent Protection (OCP)** and **Overvoltage Protection (OVP)** for enhanced reliability.  
- **Power-Good (PG) Indicators** for each output.  
- **Synchronous Rectification** for improved efficiency.  
- **Low-Dropout (LDO) Mode** for improved transient response.  
- **Thermal Shutdown Protection** to prevent overheating.  

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