Description and Introduction

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

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX253ESA+T  
- **Package:** 8-SOIC (150mil)  
- **Type:** Transformer Driver  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Output Voltage:** Up to 350V (with external transformer)  
- **Frequency Range:** Adjustable (external components dependent)  
- **Current Consumption:** Typically 2.5mA (standby)  
- **Output Current:** Up to 200mA (peak)  

### **Descriptions:**
- The MAX253ESA+T is a monolithic transformer driver designed for isolated power supply applications.  
- It integrates an oscillator, power switch, and control circuitry to drive an external step-up transformer.  
- Suitable for generating high voltages from low-voltage inputs in applications like telecom, industrial, and medical devices.  

### **Features:**
- **High-Voltage Generation:** Capable of driving transformers to produce up to 350V.  
- **Low Power Consumption:** Efficient operation with minimal standby current.  
- **Adjustable Frequency:** Oscillator frequency can be set using external components.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Overcurrent Protection:** Built-in protection against excessive output current.  
- **Compact Design:** Small SOIC package for space-constrained applications.  

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