Description and Introduction

Advanced Regulating Pulse Width Modulators 16-PDIP 0 to 70 The UC3524ANG4 is a pulse width modulation (PWM) controller manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)
- **Part Number:** UC3524ANG4
- **Type:** PWM Controller IC
- **Package:** PDIP-16 (Plastic Dual In-Line Package)
- **Operating Temperature Range:** -25°C to +85°C
- **Supply Voltage (VCC):** 8V to 40V
- **Output Current (Per Channel):** 100mA (sink/source)
- **Switching Frequency:** Adjustable up to 300kHz
- **Duty Cycle Range:** 0% to 45% (adjustable)
- **Reference Voltage:** 5V (±1%)
- **Error Amplifier Gain Bandwidth:** 3MHz (typical)

### **Descriptions:**
- The UC3524ANG4 is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications.
- It features two alternating output drivers for push-pull or single-ended configurations.
- Includes an onboard 5V reference, error amplifier, oscillator, and PWM comparator.
- Suitable for voltage-mode control in switching power supplies.

### **Features:**
- **Dual Output Drivers:** Allows for push-pull or single-ended operation.
- **Adjustable Frequency:** Set via external resistor and capacitor.
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low supply conditions.
- **Current Limiting:** Built-in protection against overcurrent conditions.
- **Soft-Start Capability:** Reduces inrush current during startup.
- **Synchronous Operation:** Multiple ICs can be synchronized.
- **Wide Supply Voltage Range:** Supports 8V to 40V input.

This device is commonly used in power converters, inverters, and regulated power supplies.
