DESCRIPTION

The TS3310 is a low power boost converter with an industry-leading low quiescent current of 150nA, enabling ultra long battery life in systems operating from a variety of battery sources. The TS3310 is the industry’s only boost converter to specify its no-load supply current with an actively switching boost engine, providing a more accurate picture of supply current during normal operation. The TS3310 boosts input voltages from 0.9V-3.6V to one of eight user-selectable output voltages ranging from 1.8V to 5.0V. The TS3310 includes two outputs: (a) an always-on primary output and (b) a user-enabled, load-switched secondary output designed to power burst-on loads operating at low duty cycles, such as a ZigBee radio. The TS3310 external component count includes 1 inductor and 3 capacitors – design of its boost regulator does not require an external rectifier diode, thereby saving additional system cost. 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 boost start-up current does not cause the input source to sag.

The extremely low quiescent current combined with a secondary output load switch makes the TS3310 an ideal choice for applications where a burst-on load can be periodically powered from the switched output. In this way, the burst-on load is disconnected from the output storage capacitor when it is turned off, preventing the burst-on load’s leakage current from discharging the output storage capacitor.

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.
