USING THE EVALUATION BOARD

INITIAL SETUP

Set the input supply to a voltage between

2.5V to 5.5V and connect it to VIN and GND

connectors on the left side of the evaluation

board. Connect the load to the VOUT and GND

connectors on the right hand side of the

board. Check to make sure that jumper J1 is

set to VIN. The board will power-up and

regulate to the desired output voltage VOUT

set by the feedback resistors. The board will

operate with a load current IOUT of up to

800mA.

JUMPER J1 FUNCTION

Jumper J1 can be used to either short EN pin

to VIN or to GND. The Board is supplied from

MaxLinear with the jumper set to connect EN

to VIN.

VOUT PROGRAMMING

The SP6669 has a dynamically programmable

output voltage using 2 feedback resistors to

control the output voltage:
