FEATURES Ultra-Efficient Boost Converter: Active Mode, No-load Supply Current: 150nA Efficiency: Up to 92% Input Voltage Range: 0.9V-3.6V Delivers up to 35mA at 3VSTORE from 1.2VIN Single-inductor, Discontinuous Conduction Mode Operation No External Schottky Diode Required Pin-Selectable Output Voltages: 1.8V, 2.1V, 2.5V, 2.85V, 3V, 3.3V, 4.1V, and 5V User-enabled Secondary Output Load Switch 10-Pin, Low-Profile, 2mm x 2mm TDFN Package APPLICATIONS Coin Cell-Powered Portable Equipment Single Cell Li-ion or Alkaline Powered Equipment Solar or Mechanical Energy Harvesting Wireless Microphones Wireless Remote Sensors RFID Tags Blood Glucose Meters Personal Health-Monitoring Devices ZigBee Radio Enabled Devices Low-Energy Bluetooth Radio Enabled Devices DESCRIPTION The TS3310 is a low power boost switching regulator with an industry leading low quiescent current of 150nA. The 150nA is the actual current consumed from the battery while the output is in regulation. The TS3310’s extremely low power internal circuitry consumes 90nA on average, with periodic switching cycles which service the load occurring at intervals of up to 25 seconds, together yielding the average 150nA. The TS3310 steps up input voltages from 0.9V to 3.6V to eight selectable output voltages ranging from 1.8V to 5V. The TS3310 includes two output options, one being an always-on storage output while the additional output is an output load switch that is designed to supply burst-on loads in a low duty cycle manner. The TS3310 operates in Discontinuous Conduction Mode with an on-time proportional to 1/VIN, thereby limiting the maximum input current by the selection of the inductor value, ensuring the input current does not drag down the input source. The extremely low quiescent current combined with the output load switch make the TS3310 an ideal choice for applications where the load can be periodically powered from the output, while being disconnected from the output storage capacitor when the load is powered off to isolate the load’s leakage current. The TS3310 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, thermally-enhanced 10-pin 2x2mm TDFN package with an exposed back-side paddle.
