DESCRIPTION

The TK65025 Low Power Step-Up DC-DC converter is designed for portable battery-powered systems, capable of operating from a single battery cell down to 0.9 V. The TK65025 provides the power switch and the control circuit for a boost converter. The converter takes a DC input and boosts it up to 3 volts. This regulated 3 volt output is typically used to supply power to a microprocessor-controlled system.
