Description and Introduction

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

### **Specifications:**
- **Manufacturer:** Intersil (INFERSIL)  
- **Part Number:** ISL6530CB-T  
- **Type:** PWM Controller for Synchronous Buck Converters  
- **Input Voltage Range:** 4.5V to 5.5V (VCC)  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** 300kHz (typical)  
- **Duty Cycle Range:** 0% to 100%  
- **Output Drive Current:** 2A (peak)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**
- The ISL6530CB-T is a high-performance PWM controller designed for synchronous buck DC-DC converters.  
- It provides precise voltage regulation for microprocessor and other low-voltage applications.  
- The device integrates MOSFET drivers and protection features for reliable power supply designs.  

### **Features:**  
- **Voltage Mode Control:** Ensures stable output regulation.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Programmable Soft-Start:** Prevents inrush current at startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load currents.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Power-Good Output:** Monitors output voltage status.  
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  

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

Application Scenarios & Design Considerations

Dual 5V Synchronous Buck Pulse-Width Modulator (PWM) Controller for DDRAM Memory VDDQ and VTT Termination

Alternative Part Number

  • LM5642MTCX --: Dual synchronous buck controller with similar dual-output PWM architecture and voltage-mode control, suitable as a functional substitute for the ISL6530 in multi-rail power designs.
  • TPS51124RGER --: Dual-channel synchronous buck controller offering comparable per-channel gate drive and feedback reference, usable as a drop-in style replacement with minor layout adjustments.
  • MIC2130YML --: Dual PWM buck controller with similar supply range and output drive capability, providing a viable alternative when the ISL6530 is unavailable.
  • TPS51116PWP --: Dual-output DDR memory power controller with integrated LDO, functionally similar to the ISL6530 dual PWM controller and widely available.
  • RT8206BGQW --: Dual synchronous buck controller for DDR memory supplies, comparable feature set and pin-compatible class replacement.
  • AP6530MP --: Dual-channel PWM controller suitable for memory/VTT power rails, offering similar voltage regulation capability as a fallback option.
