The 2.2V powers an external microprocessor, while the main output is programmed to one of four fixed voltages to wireless transmitter or sensors. The power good indicator signals that the main output voltage is within regulation. A second output can be enabled by the host. LTC3108-1 Ultralow Voltage Step-Up Converter and Power Manager voltage boost converter development board The LTC3108-1 is a highly integrated DC/DC converter ideal for harvesting and managing surplus from extremely low input voltage sources such as TEGs (thermoelectric generators), thermopiles and small solar cells. -up topology operates from input voltages as low as 20mV.Using a small step-up transformer, the LTC3108-1 provides a complete power management solution for wireless sensing and data acquisition. A storage capacitor provides power when the input voltage source is unavailable. Extremely low quiescent current and high efficiency design the fastest possible charge times of the output reservoir capacitor. The LTC3108-1 is functionally equivalent to theLTC3108 except for its fixed VOUT options., Weight: 0.01322773572 Pounds, Manufacturer: JAVERGGN
