2A, 2MHz, 28V Boost/SEPIC/Inverting DC/DC Converter Launched

Linear Technology Korea (CEO Hong Sa-kwak) announced the launch of LT8335, a current-mode, 2MHz step-up DC/DC converter with an integrated 2A, 28V switch.

The product operates in an input voltage range of 3V to 25V and is suitable for applications that provide input sources from single-cell lithium-ion inputs to automotive input ranges. The LT8335 can be configured as a boost, SEPIC, or inverting converter.

The product operates at a fixed 2MHz switching frequency, enabling designers to minimize external component size and avoid important frequency bands such as AM radio. Burst Mode® operation reduces quiescent current to just 6µA while maintaining output ripple below 15mVP-P. The combination of a 3mm x 2mm DFN package and compact external components ensures a very small form factor while minimizing solution cost.


The LT8335's 170mΩ switch delivers over 90% efficiency, while programmable UVLO (undervoltage lockout) maximizes system performance.

A single feedback resistor sets the output voltage regardless of whether the output is positive (+) or negative (–), minimizing external components. Additionally, the product includes features such as internal compensation, soft start, frequency foldback, and thermal shutdown protection.

The LT8335EDDB is supplied in a 3mm x 2mm DFN-8 package. The industrial temperature (–40°C to 125°C) version LT8335IDDB is also available. Pricing starts at $2.55 per unit at quantities of 1,000 units. Both versions are available for immediate delivery.
