Key Features
- Multi-topology operation—boost, SEPIC, and inverting—from a single IC reduces BOM count for designs needing positive or negative regulated rails
- Low quiescent current extends battery life in portable applications powered from 3 V to 25 V input rails
- 2 A, 28 V integrated switch with current-mode PWM control enables fast load transient response and simple loop compensation
Applications
The LT8335EDDB#TRMPBF is ideal for portable and battery-powered systems requiring flexible DC-DC conversion, such as industrial handheld instruments, wearable devices, and IoT sensor nodes that must generate both positive and negative supply rails from a single battery. Its SEPIC topology capability allows operation from input voltages below or above the output, making it valuable in automotive 12 V systems needing regulated 5 V or 3.3 V rails across a wide supply range. The compact 8-pin DFN footprint minimizes PCB area in space-constrained designs such as medical monitors and portable communications equipment.

Frequently Asked Questions
What input voltage range does the LT8335EDDB#TRMPBF support, and what switch rating does it integrate?
The LT8335EDDB#TRMPBF accepts input voltages from 3 V to 25 V and integrates a 2 A, 28 V power switch internally, eliminating the need for an external switching transistor. This makes it straightforward to build boost, SEPIC, and inverting converters for both single-cell lithium-ion and multi-cell battery applications within a compact 8-pin DFN package.
How does the LT8335 SEPIC topology benefit systems where the input voltage can be above or below the output?
In SEPIC configuration, the LT8335 can regulate a fixed output voltage of, for example, 5 V from an input that varies from 3 V to 25 V, covering scenarios like a LiPo battery discharging from 4.2 V down to 3.0 V while the load requires a stable 5 V rail. This eliminates the need for separate boost and buck converters, saving at least 30% PCB area in typical portable designs.
What switching frequency range does the LT8335EDDB#TRMPBF support, and how does it affect component selection?
The LT8335 supports a programmable switching frequency typically set between 100 kHz and 2 MHz using a resistor on the RT pin. Higher frequencies such as 1 MHz allow inductors as small as 2.2 µH and ceramic output capacitors below 10 µF, while lower frequencies around 200 kHz improve efficiency by reducing switching losses in high-current boost or SEPIC designs.
