TC125 - PFM Step-Up DC/DC Regulators

Datasheet Summary

Description

The TC125/126 step-up (Boost) switching regulators furnish output currents to a maximum of 80 mA (VIN = 2V, VOUT = 3V) with typical efficiencies above 80%.

These devices employ pulse frequency modulation (PFM) for minimum supply current at low loads.

Features

  • Assured Start-up at 0.9V.
  • PFM (100 kHz Max. Operating Frequency).
  • 40 μA Maximum Supply Current (VOUT = 3V @ 30 mA).
  • 0.5 μA Shutdown Mode (TC125).
  • Voltage Sense Input (TC126).
  • Requires Only Three External Components.
  • 80 mA Maximum Output Current.
  • Small Package: 5-Pin SOT-23.
