LT8335EDDB#PBF

Overview

The LT8335EDDB#PBF is a current mode DC/DC converter manufactured by Analog Devices Inc. in an 8-pin DFN EP package. It supports Boost, SEPIC, and Inverting topologies with a 2A output current capability and a 28V switch rating. The input voltage range spans from 3V to 25V, while the maximum output voltage reaches 28V. Quiescent current is specified at 6uA typical, with a shutdown supply current of 5.5uA. The device operates at a fixed switching frequency of 2MHz and 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 for positive or negative output generation.
Integrated 2A synchronous switch rated for 28V operation.
Ultra-low quiescent current consumption of 6uA typical.
Fixed 2MHz switching frequency enables compact external component sizing.

Applications

Inverting power supplies converting positive inputs to negative rails
Boost converters for battery-powered systems
SEPIC applications requiring wide input voltage ranges

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the EDDB variant matches the required thermal performance and operating temperature range. Ensure the 8-lead DFN footprint aligns with the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component for designs requiring low standby power and flexible topology configuration. The 2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 2A peak current capability meets the load requirements for the chosen boost, SEPIC, or inverting application.

Part Context

This part belongs to the LT8335 series of micropower synchronous converters. It shares family features such as low IQ operation and single-feedback pin flexibility with other variants like the LT8335IDDB#TRMPBF. The primary distinction lies in the specific thermal grade and packaging format associated with the EDDB designation.
