TPS54526RSAR  

DC Switching Voltage Regulators

TPS54526RSAR is a high-efficiency synchronous step-down (buck) converter with integrated power MOSFETs. It is designed to provide a regulated output voltage from a wide range of input voltages. The device is suitable for a variety of applications, including automotive, industrial, and telecom systems.

Description:

The TPS54526RSAR is a highly integrated, high-efficiency step-down converter that can operate from a wide input voltage range of 4.5V to 60V. It features a synchronous rectification mode, which allows for high efficiency over a wide load range. The device is available in a small, thermally enhanced PowerPad package, making it suitable for space-constrained applications.

Features:

1. Wide input voltage range: 4.5V to 60V
2. High efficiency: up to 96% efficiency
3. Synchronous rectification mode for improved efficiency at light loads
4. Integrated power MOSFETs for reduced external component count
5. Thermally enhanced PowerPad package for improved thermal performance
6. Programmable soft-start and output voltage tracking
7. Over-current, over-temperature, and thermal shutdown protection
8. Low quiescent current: 2.5µA (typical)

Applications:

1. Automotive systems, such as infotainment systems, instrument clusters, and lighting control
2. Industrial systems, such as motor control, sensor power supplies, and programmable logic controllers (PLCs)
3. Telecommunication systems, including base stations, routers, and switches
4. General-purpose power supply applications, such as battery chargers, portable devices, and backup power systems
5. Distributed power systems for point-of-load (POL) or motherboard power regulation

In summary, the TPS54526RSAR is a versatile, high-efficiency step-down converter that can be used in a wide range of applications, from automotive and industrial systems to telecom equipment and general-purpose power supplies. Its integrated power MOSFETs, synchronous rectification mode, and thermally enhanced package make it an ideal choice for space-constrained and high-efficiency applications.
