PART NUMBER DESCRIPTION COMMENTS
LTC3105 400mA Step-Up Converter with 250mV
Start-Up and Maximum Power Point Control
A High Efficiency Step-Up DC/DC Converter That Can Operate from Input Voltage As
Low As 200mV. A 250mV Start-Up Capability and Integrated Maximum Power Point
Controller (MPPT) Enables Operation Directly from Low Voltage, High Impedance
Alternative Power Sources Such As Photovoltaic Cells, Thermoelectric Generators
(TEGs) and Fuel Cells. A User Programmable MPPC Set Point Maximizes the Energy
That Can Be Extracted from Any Power Source. Burst Mode
®
Operation, with a
Proprietary Self Adjusting Peak Current, Optimizes Converter Efficiency and Output
Voltage Ripple Over All Operating Conditions.
LTC3108/
LTC3108-1
Ultralow Power Step-Up Converter and Power
Manager
A Highly Integrated DC/DC Converter Ideal for Harvesting and Managing Surplus
Energy from Extremely Low Input Voltage Sources Such As TEGs (Thermoelectric
Generators), Thermopiles and Small Solar Cells. The Step-Up Topology Operates
from Input Sources As Low As 20mV. The LTC3108 is Functionally Equivalent to the
LTC3108-1 Except for its Unique Fixed V
OUT
Options.
