Description and Introduction

Regulating Pulse Width Modulators The UC3527AN is a high-performance PWM controller manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Type:** PWM Controller  
- **Topology:** Push-Pull, Half-Bridge, Full-Bridge  
- **Operating Frequency:** Up to 500 kHz  
- **Input Voltage Range:** 8V to 35V  
- **Output Current (Source/Sink):** 200mA / 400mA  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5 MHz  
- **Package:** 16-Pin DIP (Dual In-Line Package)  

### **Descriptions:**  
The UC3527AN is a pulse-width modulation (PWM) controller designed for high-frequency power supply applications. It provides precise control for push-pull, half-bridge, and full-bridge converters. The device includes an onboard oscillator, error amplifier, and high-current totem-pole outputs for driving power MOSFETs or IGBTs.  

### **Features:**  
- Adjustable dead-time control for shoot-through prevention  
- Soft-start capability for controlled power-up  
- Under-voltage lockout (UVLO) protection  
- High-speed error amplifier for fast transient response  
- Synchronizable oscillator for multi-phase operation  
- Precision reference voltage (5V ±1%)  
- Current-limiting and shutdown protection  

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