LT1054LCS8#PBF, DC/DC Adjustable Charge Pump Voltage Converter, Inverter, Regulator 3.5V to 7V in, 125mA out, SOIC-8
The LT1054LCS8#PBF is a monolithic bipolar switched-capacitor charge-pump Voltage Converter with regulator. The LT1054 provides higher output current than previously available converters with significantly lower voltage losses. An adaptive switch driver scheme optimizes efficiency over a wide range of output currents. Total voltage loss at 100mA output current is typically 1.1V. This holds true over the full supply voltage range of 3.5 to 15V. Quiescent current is typically 2.5mA. The LT1054 also provides regulation, a feature not previously available in switched-capacitor voltage converter. By adding an external resistive divider a regulated output can be obtained. This output will be regulated against changes in both input voltage and output current. The LT1054 can also be shut down by grounding the feedback pin. Supply current in shutdown is less than 100µA. The oscillator pin can be used to adjust the switching frequency or to externally synchronize the LT1054.
• Reference and error amplifier for regulation
• External shutdown
• External oscillator synchronization
