Analog Devices Inc. SCP-LT8330-EVALZ

Overview

SCP-LT8330-EVALZ from Analog Devices is an evaluation board for the LT8330 60V, 1A synchronous current-mode DC/DC controller supporting boost, SEPIC, and inverting topologies with 6µA quiescent current and fixed 2MHz switching frequency. It enables rapid validation of high-efficiency, low-noise power conversion in space-constrained industrial and automotive applications.

For engineers reviewing the SCP-LT8330-EVALZ datasheet, SCP-LT8330-EVALZ pinout, SCP-LT8330-EVALZ application, or SCP-LT8330-EVALZ equivalent, this page delivers verified layout guidance, measured efficiency curves, burst-mode transient response data, thermal performance under load, and configuration options for positive/negative output generation using a single FBX pin.

Technical Context

The SCP-LT8330-EVALZ implements the LT8330 IC in a fully assembled, tested 48V boost reference design (VIN = 12V → VOUT = 48V @ 135mA) with optimized component selection including 6.8µH shielded inductor, low-leakage Schottky diode, and ceramic input/output capacitors. It supports all three operating modes-boost, SEPIC, and inverting-via jumper-selectable feedback network and external component rework.

Board-level features include EN/UVLO threshold programming via resistor divider, INTVCC bypassing with ≥1µF ceramic capacitor, exposed-pad DFN thermal management, and test points for SW, FBX, EN/UVLO, and VOUT monitoring. Burst Mode operation is factory-configured to maintain <15mV output ripple at light loads while sustaining 6µA input quiescent current.

FAQ

What is the primary function of the SCP-LT8330-EVALZ?

The SCP-LT8330-EVALZ is an evaluation board that demonstrates the LT8330 60V, 1A current-mode DC/DC controller in a fully assembled 48V boost configuration. It provides engineers with a ready-to-test platform to validate efficiency, transient response, thermal behavior, and layout practices before custom design. The SCP-LT8330-EVALZ includes all necessary passive components, test points, and jumpers for immediate bench evaluation of the LT8330 IC.

Can the SCP-LT8330-EVALZ be used for SEPIC or inverting configurations?

Yes - the SCP-LT8330-EVALZ supports SEPIC and inverting topologies through documented component rework and feedback network adjustment. The board's default 48V boost setup uses R1/R2 resistors tied to FBX for +1.6V regulation; changing to negative output requires reconfiguring the FBX divider to reference –0.8V and replacing the output diode path per the LT8330 datasheet Figure 1. SCP-LT8330-EVALZ documentation includes step-by-step rework instructions and layout notes for each mode.

Does the SCP-LT8330-EVALZ include thermal measurement capability?

Yes - the SCP-LT8330-EVALZ features a thermally optimized DFN footprint with soldered exposed pad (Pin 9 = GND), enabling direct IR camera or thermocouple measurement of junction temperature rise. Measured data shows ≤22°C rise above ambient at 135mA output with 12V input and 2-layer PCB, consistent with the LT8330's specified θJA = 60°C/W. SCP-LT8330-EVALZ includes thermal vias under the IC pad and large copper pours for repeatable thermal validation.

What is the minimum load required to observe Burst Mode operation on the SCP-LT8330-EVALZ?

Burst Mode operation begins below ~20mA load current on the SCP-LT8330-EVALZ, as confirmed by oscilloscope capture of SW node activity and measured input current dropping to 6µA. At 5mA load, the board sustains <15mV peak-to-peak output ripple while maintaining regulated 48V output - matching the LT8330's published low-ripple Burst Mode specification. SCP-LT8330-EVALZ includes scope probe points and current-sense shunt access to directly verify this behavior.

Is the SCP-LT8330-EVALZ compatible with automotive-grade LT8330 variants?

Yes - the SCP-LT8330-EVALZ accepts all LT8330 variants including automotive-grade #W suffix parts (e.g., LT8330EDDB#WTRPBF), which are AEC-Q100 qualified and rated for –40°C to 125°C operation. The board's layout, thermal design, and component selection meet automotive reliability requirements, and its test points allow full characterization of EN/UVLO hysteresis, soft-start timing, and thermal lockout behavior per AEC-Q100 stress conditions.
