  • Output Voltage Range: Up to 40V
  • Switching Frequency: 1.2MHz
  • Maximum Output Current: 1A (depends on input/output conditions)
  • Operating Temperature Range: -40°C to +85°C
  • Package: SOT-23-5
  • Efficiency: Up to 87%
  • Shutdown Current: <1µA
  • Internal Switch Current Limit: 1.5A (typical)

Descriptions:

The LT1931AES5 is a high-efficiency, fixed-frequency step-up DC/DC converter designed for applications requiring a regulated output voltage higher than the input supply. It features an internal NPN switch, minimizing external component count. The device operates at a high switching frequency, allowing the use of small inductors and capacitors.

Features:

  • Wide Input Voltage Range: 1.2V to 16V
  • Adjustable Output Voltage (up to 40V)
  • Low Shutdown Current (<1µA)
  • Internal Soft-Start
  • Current Mode Control for Improved Stability
  • Thermal Shutdown Protection
  • Small SOT-23-5 Package

The LT1931AES5 is commonly used in battery-powered systems, LCD bias supplies, and other applications requiring a compact boost converter solution.
