PULSE-WIDTH-MODULATION CONTROL CIRCUITS The TL495CN is a switching regulator controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Type:** Adjustable  
- **Topology:** Buck, Boost, Flyback, Inverting  
- **Output Voltage Range:** Adjustable (depends on external components)  
- **Output Current:** Up to 500mA (with external transistor)  
- **Switching Frequency:** Adjustable (typically up to 300kHz)  
- **Input Voltage Range:** 4.5V to 40V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Pin PDIP (Plastic DIP)  

### **Descriptions:**  
The TL495CN is a versatile PWM (Pulse-Width Modulation) controller designed for DC-DC converter applications. It provides the necessary control functions for step-up (boost), step-down (buck), and inverting power supply configurations. The device includes an on-board error amplifier, a voltage reference, and a PWM comparator for precise regulation.  

### **Features:**  
- Adjustable output voltage  
- On-chip 5V reference voltage (±2% accuracy)  
- Single-ended or push-pull output drive  
- Undervoltage lockout (UVLO) protection  
- Adjustable dead-time control  
- Current-limiting capability  
- Wide input voltage range  

The TL495CN is commonly used in power supply designs, battery chargers, and DC-DC converters.
