The internal oscillator of the LT1054 runs at a nominal frequency of 25kHz. Supply current in shutdown is less than 100μA. ![]() The LT1054 can also be shut down by grounding the feedback pin. ![]() ![]() This output will be regulated against changes in input voltage and output current. By adding an external resistive divider, a regulated output can be obtained. This holds true over the full supply voltage range of 3.5V to 15V. Total voltage loss at 100mA output current is typically 1.1V. An adaptive switch drive scheme optimizes efficiency over a wide range of output currents. ![]() It provides higher output current then previously available converters with significantly lower voltage losses. The LT1054 is a monolithic, bipolar, switched-capacitor, voltage converter, and regulator. LT1054 Switched-Capacitor Converter Block Diagram
