- **Supply Current (Typical):** 10mA  

### **Descriptions:**
The UC3524ADWTRG4 is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications. It provides precise voltage regulation through pulse-width modulation and includes features such as an onboard oscillator, error amplifier, and dual alternating outputs.  

### **Features:**
- **Adjustable Frequency Operation** – Allows for external oscillator timing control.  
- **Dual Output Drivers** – Supports push-pull or single-ended configurations.  
- **Onboard 5V Reference** – Stable voltage reference for feedback control.  
- **Current-Limiting Capability** – Protects against overload conditions.  
- **Soft-Start Functionality** – Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO)** – Ensures proper operation within voltage range.  
- **Wide Input Voltage Range** – Suitable for various power supply designs.  

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