TPS43350QDAPRQ1  

DC DC Switching Controllers

The Texas Instruments TPS43350QDAPRQ1 is a highly integrated, step-down (buck) switching regulator that offers high efficiency and a wide input voltage range. It is designed to provide a stable output voltage for a variety of applications, including automotive, industrial, and telecom systems.

Description:

The TPS43350QDAPRQ1 is a compact, 16-pin package that includes an internal power MOSFET, a high-side current sense, and a low-side gate drive. It also features a built-in under-voltage lockout (UVLO) and over-current protection (OCP) to ensure safe operation.

Features:

1. Wide input voltage range (4.5V to 60V)
2. High efficiency (up to 96%)
3. Low quiescent current (35µA)
4. Internal power MOSFET
5. High-side current sense and low-side gate drive
6. Under-voltage lockout (UVLO)
7. Over-current protection (OCP)
8. Thermal shutdown
9. Small package size (16-pin QFN)

Applications:

1. Automotive systems (infotainment, lighting, and power management)
2. Industrial control systems (motor drives, sensors, and power supplies)
3. Telecommunication systems (base stations, routers, and switches)
4. Portable electronics (smartphones, tablets, and laptops)
5. Medical devices (patient monitoring, diagnostic equipment, and wearable devices)
6. LED lighting (streetlights, automotive headlights, and general illumination)
7. Power-over-Ethernet (PoE) systems

The TPS43350QDAPRQ1 is a versatile and efficient switching regulator that can be used in a wide range of applications where a stable output voltage is required. Its compact size, high efficiency, and integrated features make it an ideal choice for space-constrained and power-sensitive applications.
