AN-1202 LM2698 Demo Board
1 Introduction
A printed circuit board (PCB) has been developed to aid in the design and evaluation of the LM2698 DC-
DC boost converter. This document contains information about the board.
2 General Description
The LM2698 is a general purpose, high frequency DC-DC converter. This board is intended to
demonstrate the primary advantages of the LM2698. The LM2698 is able to operate at 1.25 MHz
switching frequency, yielding extremely high power density. The low R
DS(ON)
internal MOSFET allows for
high conversion efficiency. It uses a current mode control scheme, giving superior line and load regulation.
The LM2698 is a Simple Switcher
®
, which includes Switchers Made Simple software for fast, effective
designs.
The LM2698 demo board operates with the following parameters:
4.5 V ≤ V
