LM3478MA/NOPB General Description
In addition to its advanced features, the LM3478MA/NOPB includes built-in safeguards such as thermal shutdown, short-circuit protection, and overvoltage protection, ensuring reliable and secure operation. The controller also boasts a power-saving shutdown mode that reduces total supply current to just 5 µA, making it a cost-effective and energy-efficient solution for various applications. Furthermore, the internal soft-start function helps limit inrush current during start-up, prolonging the lifespan of connected components
Features
- High-Efficiency Synchronous Buck Converter
- Soft-Switching Pulse-Width Modulation Control
- Low-Dropout Linear Regulator with High Output Current
- Fixed-Frequency Mode Operation for Fast Transient Response
- Adjustable Frequency PWM Control for Wide Range Applications
- Undervoltage Lockout Prevents Damaging Overcurrent Conditions
