Texas Instruments has introduced a 2 MHz DC-DC boost converter that operates at 5 μA quiescent current, while maintaining a high efficiency at light load conditions. The integrated circuit supports an input voltage of 0,7 to 5,5 V and an output voltage range of 1,8 to 5,5 V, extending battery life in low-power microcontroller-based designs, such as single AA or coin-cell alkaline applications.
The TPS61220, which comes in a small SC-70 package, provides full battery capacity utilisation of a portable system, because of its ability to start up with a 0,7 V input voltage into a connected load. Based on a hysteretic, off-time control method, the device uses synchronous rectification to maintain more than 85% power efficiency at low operating current. This allows microcontroller-based applications to extend battery life by maintaining efficient standby operation.
The IC provides output current up to 50 mA at 5 V output, and discharges the system’s lithium-ion battery down to 2,5 V. Output voltage can be programmed by an external resistor divider, or is fixed internally on the chip. In addition, the converter can be disabled to minimise battery drain.
