Description and Introduction

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6526IBZ is a power supply controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** INTERSIL  
- **Part Number:** ISL6526IBZ  
- **Package:** SOIC-16  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable (via external components)  
- **Switching Frequency:** 300kHz (typical)  
- **Number of Outputs:** Dual (PWM controller for two synchronous buck regulators)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The ISL6526IBZ is a dual synchronous buck PWM controller designed for generating regulated supply voltages in high-performance applications. It provides precise voltage regulation for two independent outputs, making it suitable for motherboards, graphics cards, and other power management systems. The device integrates high-side and low-side MOSFET drivers, reducing external component count.

### **Features:**  
- Dual synchronous buck PWM controllers  
- Integrated high-side and low-side MOSFET drivers  
- Adjustable output voltage via external feedback resistors  
- Overvoltage protection (OVP)  
- Undervoltage lockout (UVLO)  
- Soft-start functionality  
- Current-mode control for fast transient response  
- 300kHz fixed-frequency operation  
- Thermal shutdown protection  

This information is strictly based on the manufacturer's datasheet and specifications.

Description and Introduction

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6526IBZ is a power management IC manufactured by Intersil (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Intersil (Renesas Electronics)  
- **Part Number:** ISL6526IBZ  
- **Package:** 16-Lead SOIC  
- **Input Voltage Range:** 3.3V or 5V (±10%)  
- **Output Voltage Range:** Adjustable (0.9V to 5.5V)  
- **Output Current:** Up to 6A (with external MOSFETs)  
- **Switching Frequency:** 200kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The ISL6526IBZ is a synchronous buck PWM controller designed for high-efficiency DC-DC voltage regulation. It provides precise control for step-down converters, supporting single or dual-phase operation. It includes integrated drivers for external N-channel MOSFETs, enabling high-current applications.

### **Features:**
- **Adjustable Output Voltage:** Supports 0.9V to 5.5V via external resistor divider.  
- **Programmable Switching Frequency:** 200kHz to 1MHz for flexibility in design.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Overcurrent Protection (OCP):** Uses MOSFET RDS(ON) sensing.  
- **Overvoltage Protection (OVP):** Safeguards against output voltage spikes.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Dual-Phase Capability:** Supports interleaved operation for higher power applications.
