Description and Introduction

Quad, Serial, 8-Bit DACs with Rail-to-Rail Outputs The **MAX509BCWP+** is a high-voltage, step-down switching regulator from **MAXIM Integrated**. Below are its key specifications, descriptions, and features based on factual data:

### **Manufacturer:**  
MAXIM Integrated (now part of Analog Devices)  

### **Specifications:**  
- **Input Voltage Range:** 7.5V to **76V** (with transient operation up to 100V)  
- **Output Voltage Range:** Adjustable from **1.25V to 72V**  
- **Output Current:** Up to **500mA**  
- **Switching Frequency:** **100kHz** (fixed)  
- **Efficiency:** Up to **90%**  
- **Operating Temperature Range:** **-40°C to +125°C**  
- **Package:** **20-pin Wide SOIC (SOIC_W-20)**  
- **Topology:** **Buck (Step-Down) Converter**  
- **Control Method:** **Current-Mode PWM**  

### **Descriptions:**  
- The MAX509BCWP+ is a **high-voltage, step-down DC-DC converter** designed for industrial, automotive, and telecom applications.  
- It integrates a **high-side N-channel MOSFET**, reducing external component count.  
- Features **cycle-by-cycle current limiting** and **thermal shutdown** for protection.  
- Operates in **forced-PWM or pulse-skipping mode** for improved efficiency at light loads.  

### **Features:**  
- **Wide Input Voltage Range (7.5V to 76V)**  
- **500mA Output Current Capability**  
- **Adjustable Output Voltage (1.25V to 72V)**  
- **Internal High-Side MOSFET (0.5Ω On-Resistance)**  
- **Current-Mode PWM Control**  
- **Undervoltage Lockout (UVLO) Protection**  
- **Thermal Shutdown Protection**  
- **Cycle-by-Cycle Current Limiting**  
- **Forced-PWM or Pulse-Skipping Mode**  

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