Features & Applications

TC115501EMTTR is a high-efficiency step-up DC/DC converter and operates with low input voltage or battery powered systems. The device has a start-up voltage of 0.9 V and a typical supply current of 80 µA.

Phase compensation and soft-start circuitry are included on chip. Unlike conventional PWM step-up converters, the TC115 automatically shifts to pulse frequency modulation (PFM) at low loads, resulting in reduced supply current and improved efficiency.

Features:

  • High Efficiency at Low Output Load Currents via PFM Mode
  • Assured Start-up at 0.9V
  • 80 µA (Typ) Supply Current
  • 85% Typical Efficiency at 100 mA
  • 140 mA Typical Output Current @ VIN  2.0 V
  • Low Power Shutdown Mode
  • No External Switching Transistor Needed
  • Space-Saving SOT-89 Package

Applications:

  • Pagers
  • Cellular Phones
  • Palmtops
  • 1-Cell to 3-Cell Battery Powered Systems
  • Cameras, Video Recorders
  • Local +3 V to +5 V Supplies
