COMMENTS
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.
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.
High Efficiency Step-Down DC/DC Converter with Internal High Side and
Synchronous Power Switches, Draws Only 720nA Typical DC Supply Current at No
Load. 50mA of Load Current, Accurate UVLO Disables Converter and Maintains Low
Quiescent Current State When the Input Voltage Falls Below 2.3V. 10-Lead MSE and
3mm × 3mm DFN Packages.
High Efficiency Hysteretic Integrated Buck DC/DC; 950nA Input Quiescent Current
(Output in Regulation – No Load), 520nA Input Quiescent Current in UVLO, 2.6V to
19.2V Input Operating Range; Integrated Low-Loss Full-Wave Bridge Rectifier, Up to
100mA of Output Current, Selectable Output Voltages of 1.8V, 2.5V, 3.3V or 3.6V.
Low Current Version of LTC4054, 10mA ≤ I CHG ≤ 150mA, Thermal Regulation
Prevents Overheating, C/10 Termination, with Integrated Pass Transistor.
Low Current Version of LTC4065, 15mA ≤ I CHG ≤ 250mA, 4.2V, ±0.6% Float Voltage,
High Charge Current Accuracy: 5%.
Low 450nA Operating Current, 50mA Maximum Internal Shunt Current, Boostable to
500mA with External PFET
