The XDPP1100 is a versatile digital controller that can be employed in various applications, including isolated and non-isolated DC-DC brick converters, intermediate bus converters, and telecom power supplies, as well as point-of-load converters. The controller provides flexibility through FW, and the same HW can be configured for various topologies.

This article introduces the difference between REF_600W_FBFB_XDPP1100 and EVAL_600W_FBFB_XDPP.

What is the difference between REF_600W_FBFB_XDPP1100 and EVAL_600W_FBFB_XDPP

REF_600W_FBFB_XDPP1100

EVAL_600W_FBFB_XDPP

XDPP1100-Q040 controller

XDPP1100-Q024 controller

The controller and power are soldered in a single PCB.

Separate XDPP1100-Q024 4X4 daughter card and Power card.

2EDF7275K gate driver in the Primary side.

2EDL8124G gate driver in the primary side.

This is a quarter-brick module and needs to work with a test fixture (EVAL_QB_TEST_FIX_01).

The EVAL_XDPP1100 could work without an additional board.

Limited test points at primary and secondary switching nodes and low-side gates

test points are provided to access all the IC pins, primary and secondary switching nodes and low-side gates
