Overview
The LT8335EDDB#TRPBF is a current mode DC/DC converter manufactured by Analog Devices Inc., housed in an 8-lead DFN package. It supports Boost, SEPIC, and Inverting topologies with a single feedback pin for positive or negative output generation. Key electrical parameters include a 2A output current capability, 28V switch voltage rating, and 3V to 25V input voltage range. The device operates at a 2MHz switching frequency with quiescent currents of 840uA (operating) and 5.5uA (shutdown). It functions within a temperature range of -40°C to +125°C.
Feature Summary
- Configurable as a boost, SEPIC, or inverting converter using a single feedback pin
- Capable of generating either positive or negative output voltages
- Features low quiescent current consumption for energy efficiency
Applications
- 5V to 12V input to -12V inverting converter circuits
- Battery-powered systems requiring flexible topology configuration
- Portable electronics needing compact power management solutions
Procurement Notes
Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity. Confirm availability status as supply constraints may apply to this component series.
Selection Notes
Select this component when designing circuits requiring configurable DC/DC conversion topologies within a 3V to 25V input range. Ensure the application demands a 2A output current and fits within the 28V switch voltage limit. Verify that the required operating temperature range aligns with the specified -40°C to +125°C limits for the intended environment.
Part Context
This part belongs to the LT8335 series of low IQ converters from Analog Devices. It shares family characteristics such as current mode control and single-feedback-pin flexibility with other variants like the LT8335IDDB#TRMPBF. The series is designed for applications prioritizing space savings and efficiency through high-frequency operation and integrated power switches.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Potential cross-model replacements within the same family should be evaluated based on matching switch voltage ratings and output current capabilities.
