Description and Introduction

Dimming Ballast Control, Brown-out Protection, Programmable Preheat Time, 1.8us Deadtime in a 16-lead SOIC Narrow package The IR21592S is a self-oscillating half-bridge driver IC manufactured by International Rectifier (IR). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** International Rectifier (IR)  
- **Type:** Half-Bridge Driver IC  
- **Output Current (Source/Sink):** 210mA / 420mA  
- **Supply Voltage (VCC):** 10V to 20V  
- **Operating Frequency Range:** Adjustable, typically up to several hundred kHz  
- **Dead Time Control:** Adjustable (prevents shoot-through in half-bridge configurations)  
- **Under-Voltage Lockout (UVLO):** Yes (protects against low supply voltage)  
- **Package:** SOIC-8  

### **Descriptions:**  
The IR21592S is designed for driving MOSFETs or IGBTs in half-bridge configurations. It integrates a high-side and low-side driver with a built-in oscillator, eliminating the need for an external PWM controller. It is commonly used in power supply applications, such as electronic ballasts, DC-DC converters, and motor drives.  

### **Features:**  
- **Self-Oscillating:** No external clock required  
- **Adjustable Frequency:** Set via external resistor and capacitor  
- **Programmable Dead Time:** Prevents cross-conduction  
- **High Noise Immunity:** Robust design for switching applications  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range  
- **Low Power Consumption:** Suitable for energy-efficient designs  

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