ADP2108-1.3-EVALZ: 1.3V @ 600mA, 2.3 ~ 5.5V in

Summary

The ADP2108 evaluation board is a complete 600 mA, step-down regulator solution that tests the ADP2108, a high efficiency, low quiescent current step-down, dc-to-dc converter available in WLCSP and TSOT packages. The evaluation board is available in standard voltage options. See the Ordering Guide for avail- able models.

The ADP2108 uses a proprietary high speed, current mode, constant frequency PWM control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, the ADP2108 features a power-saving, pulse frequency modulation (PFM) mode that reduces the switching frequency under light load conditions. The 3 MHz switching frequency minimizes the size of external components. Full details on the ADP2108 are provided in the ADP2108 data sheet available from Analog Devices, Inc., which should be consulted in conjunction with this data sheet.
