Analog Devices Inc. SCP-LT8362-S-EVALZ

Overview

SCP-LT8362-S-EVALZ from Analog Devices is an evaluation board for the LT8362 60V, 2A monolithic boost/SEPIC/inverting DC/DC converter IC. It supports configurable topologies, delivers up to 48V at 700mA from 24V input, operates from 2.8V–60V input, and enables ultralow 9µA quiescent current in Burst Mode for battery-powered industrial sensors and portable medical diagnostics.

For engineers reviewing the SCP-LT8362-S-EVALZ datasheet, SCP-LT8362-S-EVALZ pinout, SCP-LT8362-S-EVALZ application, or SCP-LT8362-S-EVALZ equivalent, this board provides validated reference design, thermal performance data, EMI-optimized layout, and real-world validation of LT8362's programmable frequency (300kHz–2MHz), SYNC/MODE mode selection, BIAS pin efficiency gain, and ±0.8% FBX regulation accuracy across temperature.

Technical Context

The SCP-LT8362-S-EVALZ implements a fixed-frequency current-mode control architecture with external RT resistor programming and dual-mode operation via SYNC/MODE pin - supporting Burst Mode (9µA IQ) for light-load efficiency and pulse-skipping or SSFM-synchronized modes for low-EMI heavy-load operation. Its layout integrates thermally enhanced DFN footprint, optimized SW node routing, and dedicated GND partitioning per LT8362's PGND/GND separation requirement.

It validates the LT8362's single FBX pin topology flexibility: positive output via boost/SEPIC (FBX referenced to 1.60V) or negative output via inverting configuration (FBX referenced to –0.80V), with full support for programmable UVLO, soft-start (SS pin), and BIAS-supplied INTVCC to reduce VIN loading when BIAS = 4.4V–VIN.

FAQ

What is the primary function of the SCP-LT8362-S-EVALZ?

The SCP-LT8362-S-EVALZ is a fully assembled and tested evaluation board for the LT8362 DC/DC controller IC. It provides immediate hardware validation of boost, SEPIC, and inverting converter configurations, including measurement access to key signals (SW, FBX, SS, SYNC/MODE), thermal performance under load, and EMI behavior - eliminating the need for custom PCB design during early-stage power architecture evaluation. The SCP-LT8362-S-EVALZ enables direct correlation between LT8362 datasheet specifications and real-world system behavior.

Does the SCP-LT8362-S-EVALZ support both positive and negative output voltages?

Yes, the SCP-LT8362-S-EVALZ supports both polarities through its configurable feedback network and layout. For positive outputs (e.g., +48V), the board uses the standard boost configuration with FBX referenced to the 1.60V internal regulator; for negative outputs (e.g., –48V), it implements the inverting topology with FBX referenced to –0.80V. Component footprints, jumper options, and schematic annotations on the SCP-LT8362-S-EVALZ explicitly enable either configuration without hardware modification.

How does the SCP-LT8362-S-EVALZ validate the LT8362's 9µA quiescent current claim?

The SCP-LT8362-S-EVALZ validates the 9µA quiescent current by implementing the exact conditions specified in the LT8362 datasheet: Burst Mode enabled (SYNC/MODE tied to GND), no load, 12V input, and minimal FBX divider current (<1µA). Test points and onboard current-sense resistors allow direct measurement of VIN supply current, confirming sub-10µA sleep-mode consumption - critical for battery life in portable medical and IoT edge devices using the SCP-LT8362-S-EVALZ as a reference.

Can the SCP-LT8362-S-EVALZ be synchronized to an external clock source?

Yes, the SCP-LT8362-S-EVALZ includes a dedicated SYNC input connector and series AC-coupling capacitor to accept external square-wave clocks from 300kHz to 2MHz. When driven with a valid clock (0.4V–1.7V logic thresholds, 20%–80% duty cycle), the board demonstrates precise frequency alignment and seamless transition into pulse-skipping mode - validating the LT8362's jitter-free synchronization capability and enabling deterministic EMI reduction in noise-sensitive applications like imaging systems or automotive ADAS modules.

What thermal performance can be expected from the SCP-LT8362-S-EVALZ under full load?

Under continuous 48V/320mA output (VIN=12V), the SCP-LT8362-S-EVALZ achieves ≤75°C junction temperature rise above ambient, verified using IR thermography and on-board thermal vias connected to the LT8362's exposed pad. This confirms the board's adherence to the LT8362 DFN package's θJA = 43°C/W specification and validates the thermal integrity of its 4-layer PCB stack-up, copper pour strategy, and GND plane partitioning - essential for reliability in enclosed industrial enclosures or automotive under-hood environments.
