FEATURES
s s s s s s DESCRIPTIO s Wide Input Voltage Range: 3.5V to 30V Low Quiescent Current: 7mA Internal 7.5A Switch Very Few External Parts Required Self-Protected Against Overloads Available in Standard and Surface Mount 5-Pin Packages Can Be Externally Synchronized (See LT1072 Data Sheet) APPLICATI s s s s S High Efficiency Boost Converter PC Power Supply with Multiple Outputs Battery Upconverter Negative-to-Positive Converter Identical to the popular LT1070, except for switching frequency (150kHz) and higher switch current, they can be operated in all standard switching configurations including buck, boost, flyback, and inverting. A high current, high efficiency switch is included on the die along with all oscillator, control, and protection circuitry. Integration of all functions allows the LT1268 to be built in standard 5-pin power packages. The LT1268 operate with supply voltages from 3.5V to 30V and draw only 7mA quiescent current. By utilizing current mode switching techniques, it provides excellent AC and DC load and line regulation.
