PFM Step-Up DC/DC Regulators

General Description\nThe TC125/126 step-up (Boost) switching regulators furnish output currents to a maximum of 80mA (VIN = 2V, VOUT = 3V) with typical efficiencies above 80%. These devices employ pulse frequency modula tion (PFM) for minimum supply current at low loads. They are ideal for batte • Assured Start-up at 0.9V\n• PFM (100kHz Max Operating Frequency)\n• 40µA Maximum Supply Current (VOUT = 3V @ 30mA)\n• 0.5µA Shutdown Mode (TC125)\n• Voltage Sense Input (TC126)\n• Requires Only Three External Components\n• 80mA Maximum Output Current\n• Small Package: 5-Pin SOT-23AApplications\n• ;
