- Operates from 1 V to 30 V input with pulse frequency modulation for high efficiency down to micropower quiescent currents in battery-powered systems
- Fixed 12 V output at up to 0.4 A supporting step-up, step-down, inverting, and non-inverting conversion topologies in one compact IC
- 8-pin SOIC package with minimal external components enables small footprint DC/DC converter designs for portable and handheld electronics
What is LT1073CS8-12#PBF used for?
The LT1073CS8-12#PBF is used in battery-powered instruments, handheld meters, and portable medical devices requiring a regulated 12 V output from a single-cell or multi-cell battery input as low as 1 V. Its pulse frequency modulation control technique achieves high efficiency across a wide load range, extending battery life in data loggers, field sensors, and wireless remote units. Engineers also use it in EEPROM programming supplies and LCD bias generation circuits where a compact 8-pin SOIC converter with 12 V fixed output simplifies the power stage design.

Frequently Asked Questions
What input voltage range and output current does the LT1073CS8-12#PBF support?
The LT1073CS8-12#PBF accepts input voltages from 1 V to 30 V, making it operable from a single alkaline cell at 1.5 V nominal all the way to multi-cell battery packs. The fixed 12 V output delivers up to 0.4 A continuous load current, providing up to 4.8 W regulated output power suitable for instrumentation, display backlights, and analog signal conditioning circuits.
How does pulse frequency modulation (PFM) control in the LT1073CS8-12#PBF extend battery life compared to fixed-frequency PWM?
Pulse frequency modulation in the LT1073CS8-12#PBF reduces switching events at light loads by skipping pulses rather than reducing duty cycle, lowering average switching losses and quiescent current to microamp levels below 1 mA. This results in efficiency improvements of 20% to 40% at load currents below 50 mA compared to fixed-frequency PWM converters, significantly extending battery runtime in data acquisition and remote sensing applications.
Which conversion topologies can the LT1073CS8-12#PBF implement with its 8-pin SOIC package?
The LT1073CS8-12#PBF supports step-up (boost), step-down (buck), non-inverting, and inverting converter topologies using only a few external components including an inductor, diode, and output capacitor. This flexibility allows the same 8-pin SOIC IC to serve as a 12 V boost converter from a 3.3 V to 5 V input or an inverting converter generating -12 V for dual-supply analog circuits, reducing component variety in multi-rail power supply designs.
