PMBus demonstration board

Doc ID 13286 Rev 2

runs using the resonator clock (16 MHz). If the jumper is connected between pins

2 and 3 then the application is stopped and ST7 MCU can be re-programmed.

JP4: JP4 is used to select the power supply as described below. From the JP4

side, if the jumper is connected between pins 2 and 3 then the application runs

using the direct supply given from `POWER' connector. If the jumper is connected

between pins 1 and 2 then the application runs using the DC adapter supply given

from J1.

Power settings: The demonstration board can be powered by one of the following

options:

DC adapter: Connect a DC adapter to J1. The DC adapter should supply a

minimum of 7 V and maximum of 18 V, 1 A. This supply is regulated to 5 V supply

using an L7805 regulator.

Regulated supply: The user can use a direct 3 V to 5 V supply. The supply and

Gnd points should be connected to the `POWER' connector pins 1 and 2. Here,

`POWER' connector pin 1 is referred from the JP4 jumper side (from the right

side).
