Description

The ISL9106EVAL1Z is an evaluation kit for the ISL9106

1.6MHz 1.2A low quiescent current, high efficiency

integrated step-down regulator. The ISL9106 is capable of

delivering up to 1.2A output current with an output voltage

range of 0.8V to ~V

voltage divider resistors of R

default output voltage is set to be 1.6V on the evaluation

board.

The complete ISL9106 regulator is located at the center of

the board. On the left side of the board are the connectors

for the input power source (VIN and GND). The output

connectors are located on the right side (VO and GND). The

other two test points are for the PG and RSI signals

respectively, as labelled on the board. The RSI input needs

either be driven to a low or a high logic input (Please refer to

the ISL9106 datasheet, FN6509 for more details regarding

RSI function). Do not leave the RSI input signal floating.

The open-drain PG signal is pulled up to the V

100kΩ resistor (R

or disable the IC. Jumper JP2 is the mode selection input.

Do not leave the EN or the MODE signal floating. The

evaluation board also offers one oscilloscope probe tip

connector connected to SW pin to minimize the switching

noise during the evaluation. One test point (labeled as FB) is

connected to the FB pin on the board in order to monitor the

FB voltage.

The evaluation board schematic, layout and bill-of-materials

(BOM) can be found at the end of this application note.
