Description and Introduction

1W Primary-Side Transformer H-Bridge Driver for Isolated Supplies The **MAX253EPA+** is a transformer driver IC manufactured by **MAXIM** (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** MAXIM (Analog Devices)  
- **Part Number:** MAX253EPA+  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Output Current:** Up to 350mA (peak)  
- **Switching Frequency:** Adjustable (external components determine frequency)  
- **Primary Inductance Range:** Typically used with transformers in the 1mH to 10mH range  

### **Descriptions:**
- The **MAX253EPA+** is a monolithic transformer driver designed for isolated power supply applications.  
- It is commonly used in telecom, industrial, and medical equipment where isolated power conversion is required.  
- The device includes an oscillator, gate drive circuitry, and a power switch to drive an external transformer.  
- It supports push-pull operation for efficient power transfer.  

### **Features:**
- **High-Efficiency Push-Pull Driver** for isolated power supplies.  
- **Wide Input Voltage Range** (4.5V to 5.5V).  
- **Adjustable Switching Frequency** via external components.  
- **Low-Power Standby Mode** for reduced power consumption.  
- **Integrated Power Switch** simplifies external circuitry.  
- **Thermal Shutdown Protection** to prevent overheating.  
- **Suitable for Flyback and Forward Converters.**  

This information is based solely on the manufacturer's datasheet and technical documentation. No additional guidance or suggestions are included.
