Description

The LTC1147LIS8#PBF is a high-efficiency, synchronous step-down switching regulator designed by Linear Technology, which is now part of Analog Devices. This component is engineered to deliver high performance in power conversion applications, offering a significant reduction in power losses compared to traditional regulators.

Key Features

  • High Efficiency: Capable of up to 94% efficiency, the LTC1147LIS8#PBF is designed to maximize battery life in portable devices and reduce heat dissipation in all applications.
  • Synchronous Operation: The synchronous rectification design helps in reducing switching losses and improves efficiency by replacing the diode with a low resistance N-channel MOSFET.
  • Wide Input Voltage Range: This regulator can operate with an input voltage range from 3.5V to 15V, making it versatile for a wide variety of power sources.
  • Adjustable Switching Frequency: The switching frequency can be set from 100kHz to 400kHz, allowing designers to optimize the performance based on the specific application requirements.
  • Low Dropout Operation: The LTC1147LIS8#PBF's low dropout operation ensures efficient performance even when the input voltage is close to the output voltage.
  • Stable with Ceramic Capacitors: This regulator is stable with ceramic output capacitors, which can be smaller, have lower ESR, and are more temperature tolerant than electrolytic capacitors.

Applications

The LTC1147LIS8#PBF is suitable for a broad range of applications, including but not limited to:

  • Portable electronics
  • Telecommunications
  • Industrial power supplies
  • Automotive systems

Package and Quality

The LTC1147LIS8#PBF comes in an 8-lead SOIC package, which is compact and suitable for space-constrained applications. The part is also available in a lead-free finish, adhering to the latest environmental standards and regulations such as RoHS. With Linear Technology's commitment to high-quality products, this regulator ensures reliable performance and longevity in your electronic designs.
