The UCC27284DRCR is a high-voltage, high-current, synchronous step-down regulator from Texas Instruments. It is designed to provide efficient and precise voltage regulation for a wide range of applications, including industrial, medical, and automotive systems.

Description:

The UCC27284DRCR is a monolithic power management device that integrates a high-side power MOSFET and a low-side power MOSFET to regulate the output voltage. It operates in a continuous-conduction mode (CCM) and offers a wide input voltage range of 4.5V to 60V. The device features a fixed 500kHz switching frequency, which can be synchronized to an external clock for improved noise performance.

Features:

1. High input voltage range: 4.5V to 60V
2. Wide output voltage range: 0.9V to 60V
3. Synchronous rectification for high efficiency
4. Fixed 500kHz switching frequency, with external sync capability
5. Internal soft-start and power-good signal
6. Over-current protection, over-temperature protection, and under-voltage lockout
7. Small package size: 5mm x 6mm, 24-pin thermally enhanced QFN

Applications:

1. Industrial systems: Motor drives, power supplies, and battery charging systems
2. Medical equipment: Patient monitoring devices, medical imaging systems, and portable medical instruments
3. Automotive systems: Infotainment systems, lighting control, and battery management systems
4. Telecommunications: Base stations, routers, and network switches
5. Renewable energy systems: Solar power inverters and wind turbine converters

The UCC27284DRCR is a versatile and efficient step-down regulator suitable for a wide range of high-voltage and high-current applications. Its integrated MOSFETs, wide input voltage range, and high efficiency make it an ideal choice for demanding power management requirements.
