Description and Introduction

Advanced Regulating Pulse Width Modulators The UC3524DTR is a pulse width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)
- **Part Number:** UC3524DTR
- **Type:** PWM Controller IC
- **Package:** SOIC-16
- **Operating Temperature Range:** -40°C to +85°C
- **Output Type:** Push-Pull
- **Switching Frequency:** Up to 300 kHz
- **Supply Voltage (VCC):** 8V to 40V
- **Output Current:** 100 mA (per channel)
- **Duty Cycle Range:** 0% to 45% (adjustable)
- **Reference Voltage:** 5V (±1%)
- **Error Amplifier Gain Bandwidth:** 3 MHz (typical)

### **Descriptions:**
- The UC3524DTR is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications.
- It includes an on-board oscillator, error amplifier, PWM comparator, and dual alternating output drivers.
- Suitable for push-pull, flyback, and forward converter topologies.
- Provides precise voltage regulation and current limiting.

### **Features:**
- **Adjustable Frequency:** Set via external resistor and capacitor.
- **Dual Output Drivers:** Allows for push-pull or single-ended operation.
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.
- **Soft-Start Capability:** Reduces inrush current during startup.
- **Current Limiting:** Protects against overload conditions.
- **Synchronization Capability:** Allows multiple ICs to sync to a master clock.
- **Wide Supply Voltage Range:** Supports 8V to 40V input.

This information is based on TI's official datasheet for the UC3524DTR. For detailed application notes, refer to the manufacturer's documentation.
