Evaluation Board Description

The AAT1106 evaluation board contains a fully tested

600mA, 1.5MHz Step-Down DC/DC Regulator. The circuit

has an input voltage range of 2.5V to 5.5V and four pre-

set selectable outputs (1.2V, 1.5V, 1.8V and 2.5V).

The AAT1106 comes in a small 5-pin TSOT23 package

and the board has been optimized to fit small form factor

designs. An optional TVS (SM6T6V8A) is connected

between VIN and GND so that the evaluation board can

be used in a hot-plug application. These features, plus

the nominal operating frequency of 1.5MHz allowing the

use of low profile surface mount components, make the

AAT1106 evaluation board an ideal circuit for use in

battery-powered, hand-held applications.

A schematic of the complete circuit is shown in Figure 3.

The evaluation board layer details are provided in

Figures 4, 5, 6 and 7. Table 3 provides the component

list for the AAT1106 evaluation board.
