Description

The LTC1147CS8-3.3#TRPBF is a high-performance step-down (buck) switching regulator from Linear Technology, now part of Analog Devices. This efficient and reliable integrated circuit (IC) is designed to provide a fixed output voltage of 3.3V from a higher input voltage, making it an ideal solution for various applications that require a regulated power supply with a lower voltage.

Key Features

  • High Efficiency: Capable of converting input voltages to a 3.3V output with a high efficiency rate, minimizing power loss and heat generation.
  • Adjustable Switching Frequency: The switching frequency can be programmed up to 200kHz, allowing flexibility in choosing inductors and capacitors for size, cost, and efficiency trade-offs.
  • Low Dropout Operation: The regulator can maintain output regulation with a very small difference between input and output voltages, which is beneficial during low input voltage conditions.
  • Synchronous Rectification: Offers the option for synchronous rectification, enhancing efficiency by reducing diode losses.
  • Current Mode Control: Provides excellent line and load transient response.
  • Burst Mode® Operation: Ensures high efficiency at low output currents, which is critical for battery-powered applications.
  • Thermal Protection: Features thermal shutdown to protect the device under over-temperature conditions.

Applications

The LTC1147CS8-3.3#TRPBF is suitable for a wide range of applications, including:

  • Portable devices
  • Telecommunications equipment
  • Computing devices
  • Industrial systems
  • Battery-powered gadgets

Package and Quality

The regulator is available in an 8-lead narrow SOIC package, which provides a compact footprint for space-constrained applications. The part number LTC1147CS8-3.3#TRPBF indicates that this component is provided in tape and reel packaging, which is suitable for automated pick-and-place manufacturing processes. Furthermore, it adheres to Linear Technology's high standards for quality and reliability, ensuring stable performance in a variety of operating conditions.
