Description and Introduction

Dual 5V Synchronous Buck Pulse-Width Modulator (PWM) Controller for DDRAM Memory VDDQ and VTT Termination The ISL6530CB is a power management IC manufactured by Intersil (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **NS (National Semiconductor)** – The ISL6530CB was originally designed by Intersil, not National Semiconductor. There might be confusion with similar part numbers from NS.  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable (typically used for 3.3V and 5V regulation)  
- **Switching Frequency:** 300kHz (fixed)  
- **Maximum Output Current:** 2A (for 3.3V output)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The ISL6530CB is a dual-output PWM controller designed for powering low-voltage digital ICs.  
- It integrates two synchronous buck regulators, providing regulated 3.3V and 5V outputs.  
- It includes overcurrent protection, undervoltage lockout (UVLO), and thermal shutdown.  

### **Features:**  
- Dual-output synchronous buck controller  
- Adjustable soft-start for controlled power-up  
- Integrated MOSFET drivers  
- Overcurrent protection with hiccup mode  
- Undervoltage lockout (UVLO)  
- Thermal shutdown protection  
- Fixed-frequency PWM operation (300kHz)
