- **Reference Voltage:** 5.1V (±1%)  
- **Operating Temperature Range:** -25°C to +85°C  
- **Package:** 16-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The UC1526J is a high-performance PWM controller designed for power supply applications.  
- It includes an on-board oscillator, error amplifier, PWM comparator, and dual alternating outputs.  
- Suitable for push-pull, half-bridge, and full-bridge converter topologies.  
- Features soft-start capability and shutdown control.  

### **Features:**  
- **Adjustable Frequency:** Set via external resistor and capacitor.  
- **Dual Outputs:** Alternating outputs with programmable dead time.  
- **Error Amplifier:** High-gain op-amp for feedback control.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Current Limiting:** Supports peak current limiting.  
- **Synchronization Capability:** Can sync with an external clock.  
- **Soft-Start Control:** Reduces inrush current during startup.  

This IC is commonly used in DC-DC converters, inverters, and motor control applications.
