Description

Product Overview: LTC3784EUFD#PBF

The LTC3784EUFD#PBF is a high-performance, synchronous, step-up DC/DC controller from Linear Technology, designed to regulate a constant-current or constant-voltage from a wide input voltage range. It is ideal for applications requiring a high voltage output from a low voltage input, and it is particularly well-suited for use in battery-powered systems, automotive, industrial, and telecommunications equipment.

Key Features

  • Wide Input Voltage Range: The device is capable of operating from an input voltage range of 4.5V to 38V, making it versatile for various power supply designs.
  • High Output Voltage: It can produce an output voltage up to 60V, which is beneficial for applications that require a high voltage for functions such as LED drivers or power amplifiers.
  • Constant-Current and Constant-Voltage Modes: The LTC3784EUFD#PBF can be programmed to operate in either constant-current mode for driving LEDs or constant-voltage mode for general power supply applications.
  • Powerful Gate Drivers: The integrated gate drivers are capable of driving N-channel MOSFETs, which can help in achieving high efficiency and reducing overall power loss.
  • Phase-Lockable Frequency: Its switching frequency can be synchronized to an external clock, ranging from 75kHz to 850kHz, allowing for design flexibility and noise reduction in sensitive applications.
  • Robust Protection Features: The device includes overvoltage protection, overcurrent protection, and thermal shutdown, ensuring reliable operation under adverse conditions.

Applications

The LTC3784EUFD#PBF is versatile and can be used in a variety of applications, including but not limited to:

  • Automotive and Industrial LED Lighting
  • Power Amplifiers
  • Battery-Powered Equipment
  • Energy Harvesting Systems
  • Telecommunications Power Supplies

Quality and Reliability

Linear Technology, now part of Analog Devices, is known for its commitment to manufacturing high-quality, reliable components. The LTC3784EUFD#PBF is no exception and is designed to meet the rigorous standards required by industrial and automotive applications.

Package Information

The device is available in a 28-lead (4mm × 5mm) QFN package, providing a compact solution for space-constrained applications.
