DESCRIPTION The LT ?1054 is a monolithic, bipolar, switched-capacitor voltage converter and 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 3.5V to 15V. Quiescent current is typically 2.5mA. FEATURES ■ Available in Space Saving SO-8 Package ■ Output Current: 100mA (LT1054) 125mA (LT1054L) ■ Reference and Error Amplifier for Regulation ■ Low Loss: 1.1V at 100mA ■ Operating Range:3.5V to 15V (LT1054) 3.5V to 7V (LT1054L) ■ External Shutdown ■ External Oscillator Synchronization ■ Can Be Paralleled ■ Pin Compatible with the LTC?1044/LTC7660 APPLICATIONS ■ Voltage Inverter ■ Voltage Regulator ■ Negative Voltage Doubler ■ Positive Voltage Doubler |
