LT8333RDD#PBF

Overview

The LT8333RDD#PBF is a synchronous step-up/step-down DC-DC converter manufactured by Analog Devices Inc. It supports boost, SEPIC, and inverting topologies with an input voltage range of 2.8V to 40V. The device provides a single adjustable output ranging from 0.8V to 40V, capable of delivering up to 3A of output current. It features a programmable switching frequency between 300kHz and 2MHz. The component operates within a junction temperature range of -40°C to 150°C and is housed in a 10-WFDFN package with exposed pad.

Feature Summary

Supports multiple topologies including boost, SEPIC, and inverting configurations for flexible power conversion.
Integrates internal high-side and low-side switches to minimize external component count.
Features a wide input voltage range suitable for various battery and bus supply applications.

Applications

Battery-powered portable equipment
Industrial control systems
Automotive electronics

Procurement Notes

Verify the specific suffix '#PBF' against the datasheet to confirm lead-free status and RoHS compliance requirements. Ensure the 'RDD' package code matches the required 10-WFDFN footprint dimensions. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and revision history before procurement.

Selection Notes

Select this component when designing circuits requiring both boost and buck capabilities from a single IC. Consider the 3A current limit and 40V maximum ratings against load requirements. Evaluate the thermal performance of the exposed pad DFN package for heat dissipation needs. Confirm that the operating frequency range aligns with EMI constraints and inductor size preferences.

Part Context

This part belongs to the LT8333 family of synchronous converters designed for high-efficiency power management. It differentiates itself by combining boost, SEPIC, and inverting functions in one package. The RDD variant specifies the particular tape-and-reel or tube packaging configuration and pin assignment for surface-mount assembly.
