EVAL-L99H02XP board
The EVAL-L99H02XP is composed by a motherboard and a daughterboard on which is pre-assembled the EVALL99H02XP (see the Figure 1). The system features an enhanced power management power supply functionality including various standby modes. The motherboard, based on STM8 microcontroller, provides the logic section for monitoring and driving the EVAL-L99H02XP assembled in the daughterboard. With the aim to make the board usage and setting simpler, STM provides a dedicated Graphic User Interface (GUI). This enables the user to set EVAL-L99H02XP parameters and at the same time it shows real time device information.

Hardware description and setup
This section provides a description of the main components of this evaluation kit, giving instruction for a quick setup of the system.
2.1
Components description
The evaluation kit consists of two main components:
· 1 Motherboard based on STM8A microcontroller, interfacing host PC with daughterboard. The communication with the PC is established through isolated USB.
· 1 Daughterboard assembling EVAL-L99H02XP.
The daughterboard with EVAL-L99H02XP and the motherboard are already properly plugged provided.

Motherboard schematic
A universal motherboard is used to control and drive the daughterboard containing the EVAL-L99H02XP. The motherboard has the following functions:
· USB-to-UART conversion: a FT232RL USB to serial UART interface is used to convert the data from the GUI, in the PC, in commands that are processed by the microcontroller.
· STM8AF51xAT microcontroller: it is used to convert the commands from the GUI in control signals for the L99H02XP in the daughterboard. Also it process the data received from the L99H02XP and return the results to the GUI by the USB.
· L4995R LDO: this LDO is used to convert the +12 V used to supply the motherboard to a +5 V voltage used to supply the microcontroller and the L99H02XP in the daughterboard.
· Socket and connectors to plug the daughterboard.
The motherboard schematic is shown in the following figures. Schematic and BOM of the motherboard can be found on the ST website.

Motherboard layout
The EVAL-L99H02XP motherboard was designed in a 2 layers board. Motherboard Top and Bottom layers are shown in the Figure 7 and Figure 8. Gerber files of the motherboard can be found in the ST website

Daughterboard layout
Different choice regarding the number of the layers can be used. A two-layers or an N-layers (where N can be 3 or 4) application board can be used to develop the board for the L99H02XP application.
A 4 layers solution was chosen to design the EVAL-L99H02XP daughterboard to increase the ground area on which to disperse the heat.
The Top, Inner 1, Inner 2 and Bottom layers are shown in the following figures.
Gerber files of the daughterboard can be found in the ST website.
