- **Package:** 16-Pin CERDIP (J)  
- **Operating Temperature Range:** -55°C to +125°C  
- **Input Voltage Range:** 8V to 40V  
- **Output Drive Current:** 200mA (sink/source)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Features:**  
  - Adjustable dead-time control  
  - Soft-start capability  
  - Error amplifier for feedback control  
  - Precision reference voltage (5V ±1%)  
  - Under-voltage lockout (UVLO)  
  - Synchronizable oscillator  

### **Descriptions and Features:**  
The **UC2543J** is a high-performance pulse-width modulation (PWM) controller designed for power supply applications. It provides precise control over switching regulators with features like adjustable dead-time, soft-start, and synchronization capability. The device operates over a wide input voltage range and includes protection features such as under-voltage lockout (UVLO). Its high-speed switching capability (up to 500kHz) makes it suitable for demanding power conversion applications.  

The **CERDIP (J) package** ensures reliability in harsh environments, making it ideal for military and industrial applications.  

(Note: Since Unitrode was acquired by Texas Instruments, the part may also be referenced under TI’s product listings.)
