TC125 Datasheet (Microchip Technology) - PFM Step-Up DC/DC Regulators

TC125, PFM Step-Up DC/DC Regulators

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.

They are ideal for battery-operated applications
