### **Specifications:**
- **Manufacturer:** UNITRODE (now Texas Instruments)  
- **Type:** Current-Mode PWM Controller  
- **Topology:** Supports flyback, forward, push-pull, and half/full-bridge configurations  
- **Operating Frequency:** Up to 1MHz  
- **Output Drive Current:** ±2A peak  
- **Supply Voltage (VCC):** 7V to 35V  
- **Duty Cycle Range:** 0% to 100%  
- **Soft-Start Capability:** Programmable  
- **Current Sense Input:** Adjustable current limiting  
- **Error Amplifier Bandwidth:** 5MHz  
- **Package:** 8-Pin DIP (PDIP)  

### **Descriptions:**
The UCC2807N-2 is a high-performance PWM controller designed for switching power supplies. It operates in current-mode control, providing precise regulation and fast transient response. The device includes features like soft-start, cycle-by-cycle current limiting, and an onboard error amplifier for feedback loop control.  

### **Features:**
- **High-Speed Operation:** Up to 1MHz switching frequency  
- **BiCMOS Technology:** Low power consumption and high noise immunity  
- **Current-Mode Control:** Improves loop response and simplifies compensation  
- **Programmable Soft-Start:** Reduces inrush current during startup  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within supply range  
- **Error Amplifier:** Allows flexible feedback loop design  
- **High-Current Totem-Pole Output:** Directly drives power MOSFETs
