LT1107CS8#PBF

LT1107 is a versatile micropower DC/DC converter. Supply voltage ranges from 2V to 12V in step-up mode and to 30V in step-down mode. The LT1107 functions equally well in step-up, stepdown, or inverting applications. The LT1107 is pin-for-pin compatible with the LT1111, but has a duty cycle of 70%, resulting in increased output current in many applications. Quiescent current is just 320µA, making the LT1107 ideal for power-conscious battery operated systems. The 63kHz oscillator is optimized to work with surface mount inductors and capacitors. Switch current limit can be programmed with a single resistor. An auxiliary gain block can be configured as a low-battery detector, linear post regulator, undervoltage lock-out circuit, or error amplifier. Applications include palmtop computers, 3V to 5V, 5V to 12V converters, 24V to 5V, 12V to 5V converters, LCD bias generators, peripherals and add-on cards, battery backup supplies, cellular telephones and portable instruments.

• Operates at supply voltages from 2V to 30V, consumes only 320µA supply current
• Works in step-up or step-down mode
• Only three external components required
• Low-battery detector comparator on-chip, user adjustable current limit
• Internal 1A power switch
• Comparator trip point voltage of 1.25V typical at VIN = 3V (full operating temperature range)
• 8-lead plastic SO package, operating temperature range from 0°C to 70°C
