Description and Introduction

1W Primary-Side Transformer H-Bridge Driver for Isolated Supplies The MAX253ESA+ is a transformer driver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX253ESA+  
- **Package:** 8-SOIC (150mil)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (V+):** 4.5V to 5.5V  
- **Output Current:** Up to 350mA (peak)  
- **Switching Frequency:** Adjustable (typically up to 500kHz)  
- **Duty Cycle:** 50% (typical)  
- **Logic Input Compatibility:** CMOS/TTL  

### **Description:**  
The MAX253ESA+ is a monolithic transformer driver designed for isolated power supply applications. It provides a high-efficiency, push-pull output capable of driving a center-tapped transformer. The device is optimized for low-power isolated DC-DC converters and is commonly used in telecom, industrial, and medical applications requiring galvanic isolation.

### **Features:**  
- **Push-Pull Transformer Driver:** Supports center-tapped transformer configurations.  
- **Wide Input Voltage Range:** Operates from 4.5V to 5.5V.  
- **High Output Current:** Delivers up to 350mA peak current.  
- **Adjustable Oscillator Frequency:** Allows optimization for different transformer designs.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **CMOS/TTL-Compatible Logic Inputs:** Ensures easy interfacing with microcontrollers and logic circuits.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

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