Hardware Description
The Evaluation Board has to be supplied via the pins VIN and GND in the range of 2.7V up to
5.5V.
For enabling the device jumper “EN” (J1) must be set to “on”, section F in Figure 2.
Please use the “VOUT” (BU4) or “Load” (J2) connector for connecting a load to Vout.
AS1382 supports output voltages between 0.6125 and 3.35V and additionally the device is
available with 2MHz, 3MHz, or 4MHz switching frequency.
The offered variants of AS1382 Evaluation Kit are stated under chapter 4, Ordering & Contact
Information.
