### **Descriptions:**
- The SG2525AP is a fixed-frequency PWM controller designed for switch-mode power supply applications.
- It includes an on-chip oscillator, error amplifier, PWM comparator, latch, and output drivers.
- Provides soft-start functionality, undervoltage lockout (UVLO), and shutdown capability.
- Suitable for DC-DC converters, inverters, and motor control applications.
### **Features:**
- **Adjustable Dead-Time Control:** Prevents shoot-through in bridge configurations.
- **Soft-Start Function:** Gradually increases duty cycle to prevent inrush current.
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.
- **Synchronization Capability:** Allows multiple ICs to sync to a master clock.
- **Error Amplifier:** Provides feedback loop stability.
- **Shutdown Pin:** Allows immediate disabling of outputs.
- **Double-Pulse Suppression:** Prevents multiple pulses in a single cycle.
