The 150 nA is the actual current consumed from the Efficiency up to 92% battery while the output is in regulation. The TS3310s extremely low power internal cir- Input Voltage Range: 0.9 to 5.0 V cuitry consumes 120 nA on average, with periodic switching cycles which service the Delivers up to 35 mA at V from 1.2 STORE load occurring at intervals of up to 25 seconds, together yielding the average 150 nA. V IN The TS3310/12/14 steps up input voltages from 0.9 V (TS3312: 2 V) to 5 V to sixteen Single Inductor, Discontinuous Conduction selectable output voltages ranging from 1.8 V to 5 V. The TS3310/12/14 includes two Mode Operation output options, one being an always-on storage output while the additional output is an User-Enabled Secondary Output Load output load switch that is designed to supply burst-on loads in a low duty cycle manner. Switch to Isolate Leaky Burst Loads The TS3310/12/14 operates in Discontinuous Conduction Mode with an on-time propor- tional to 1/VIN, thereby limiting the maximum input current by the selection of the induc- No External Schottky Diode Required tor value, ensuring the input current does not drag down the input source. UVLO Threshold 0.9 V (TS3310/14) The extremely low quiescent current combined with the output load switch make the 2.0 V (TS3312) TS3310/12/14 an ideal choice for applications where the load can be periodically pow- Pin-Selectable Output Voltages: ered from the output, while being disconnected from the output storage capacitor when 1.8 V, 2.1 V, 2.5 V, 2.85 V, 3 V, 3.3 V, the load is powered off to isolate the loads leakage current. 4.1 V, 5 V (TS3310) The TS3310/12/14 is fully specified over the 40 C to +85 C temperature range and is 2.1 V, 2.5 V, 2.85 V, 3 V, 3.3 V, 4.1 V, 5 V (TS3312) available in a low-profile, thermally-enhanced 10-pin 2x2 mm TDFN package with an ex- posed back-side paddle. 4 V, 4.2 V, 4.35 V, 4.5 V, 4.6 V, 4.7 V, 4.8 V, 4.9 V (TS3314) Applications 10-pin, 2 mm 2 mm TDFN Package Coin-Cell-Powered Portable Equipment Single-Cell Lithium-Ion or Alkaline Battery-Powered Equipment Solar or Mechanical Energy Harvesting Wireless Microphones Wireless Remote Sensors RFID Tags Personal Health-Monitoring Devices ZigBee Radio Enabled Devices Low-Energy Bluetooth Radio Enabled Devices silabs.com Smart.
