Key Features
- Ultra-wide 1 V to 30 V input range with pulse-frequency modulation (PFM) control enables efficient boost conversion from single-cell batteries
- Micropower quiescent current design extends battery life in sleep-mode applications with adjustable or fixed 5 V / 12 V output options
- Compact 8-pin SOIC (S8) package with minimal external components reduces total solution size for handheld and portable designs
Applications
The LT1073CS8#TRPBF is designed for battery-powered portable electronics, handheld instruments, and low-power sensor nodes requiring a regulated 5 V or 12 V output from a supply as low as 1 V. Its micropower PFM operation makes it especially suitable for applications like EEPROM programming supplies, LCD bias generators, and wireless sensor nodes where standby current below 100 µA is essential.

Frequently Asked Questions
What input voltage range does the LT1073CS8#TRPBF support, and how does this affect battery-powered designs?
The LT1073CS8#TRPBF accepts input voltages from 1 V to 30 V, allowing it to operate from a single alkaline cell down to 1 V at end of life. This wide range lets designers use the IC with 1.5 V primary cells, 3.7 V lithium cells, or multi-cell packs, maximizing battery utilization before the system shuts down.
How does the pulse-frequency modulation control mode of the LT1073CS8#TRPBF reduce quiescent current in low-load applications?
Pulse-frequency modulation skips switching cycles when the output is lightly loaded, reducing average quiescent current to well under 100 µA at standby. This makes the LT1073CS8#TRPBF far more efficient than fixed-frequency PWM converters in IoT sensors and portable instruments that spend most of their operating time in sleep mode with only microamp load currents.
For a compact LCD bias supply needing 12 V from a 3 V coin cell, does the LT1073CS8#TRPBF fit the design requirements?
Yes. The LT1073CS8#TRPBF boosts inputs from as low as 1 V up to a regulated 12 V output using its internal switch and an external inductor and diode, making it a direct fit for LCD bias generators powered by 3 V coin cells. Its 8-pin SOIC package and minimal external component count keep the total solution footprint under 1 cm² for space-constrained handheld designs.
