1 General Description
2 Key Features

A demonstration board is available to test AS7620 functionalities and performance in a standard application.

Default conditions are VIN=24V and VOUT=5V, but in principle the input voltage can range from 5V to 32V.

While the AS7620 output voltage can range from 1.2V to VIN, the demonstration board upper output voltage limitation is 15V.

The output voltage can be easily adjusted using the 0805-sized output resistor divider pads on the back of the evaluation board.

Convenient test point loops for input, output, shutdown and power monitor flags

High Voltage ceramic capacitor for output voltages of up to 15V

Micro-power LDO generates 3.3V for flag outputs, supplies up to 250mA

Single-sided assembly allows convenient backside access for modification

Large-size 0805 parallel pads for all configuration resistors

Alternate landing pads for output inductor and capacitor

Quiet GND probe point minimizes GND loop area and noise
