LT8335IDDB#PBF

Overview

The LT8335IDDB#PBF is a current mode DC/DC converter manufactured by Analog Devices Inc. in a DFN-8 package. It supports Boost, SEPIC, and Inverting topologies with a single feedback pin for positive or negative output generation. The device features a 2A switch, 28V switch rating, and operates from 3V to 25V input. Quiescent current is 840uA (operating) and 5.5uA (shutdown). Switching frequency is 2MHz. Operating temperature range is -40°C to +125°C.

Feature Summary

• Configurable as boost, SEPIC, or inverting converter using a single feedback pin
• Integrated 2A switch with 28V voltage rating
• Low quiescent current consumption of 5.5uA in shutdown mode

Applications

• Battery-powered portable equipment requiring low standby current
• Industrial systems needing isolated or inverted supply rails
• Automotive electronics operating within specified temperature ranges

Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel packaging configuration. Confirm availability status as distribution channels may report limited stock. Ensure the DFN-8 footprint matches the target PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when a single IC must support multiple converter topologies including boost, SEPIC, and inverting configurations. The 2A switch current and 28V rating suit moderate power applications. Consider the 2MHz switching frequency for size constraints and the wide input voltage range for battery applications.

Part Context

This part belongs to the LT8335 series of low IQ DC/DC converters. It integrates a 2A synchronous switch and control logic in a compact DFN-8 package. The series is designed for applications requiring flexible topology selection and low power consumption during standby periods.

Replacement Considerations

LT8335IDDB#TRMPBF shares identical electrical specifications and pinout but differs in packaging format.
