Evaluation Board for ADP2118 EVAL-ADP2118
●The evaluation (demo) board provides an easy way to evaluate the ADP2118 buck regulator. This data sheet describes how to quickly set up the board to begin collecting performance data. Full details on the ADP2118 are available in the ADP2118 data sheet, which is available from Analog Devices, Inc., and should be consulted in conjunction with this data sheet when using the evaluation board.
This data sheet also describes the design process for the ADP2118 buck regulator, including external component selection, and how to obtain the best dynamic performance.
Thermal performance is described, which provides a current derating reference for the user when the ADP2118 is operating at different ambient temperatures.
●The ADP2118 is a low quiescent current, synchronous, step-down, dc-to-dc regulator in a compact 4 mm × 4 mm LFCSP_WQ package. It uses a current mode, constant frequency pulse width modulation (PWM) control scheme for excellent stability and transient response. Under light loads, the ADP2118 can be configured to operate in pulse frequency modulation (PFM) mode that reduces switching frequency to save power.
The ADP2118 runs from input voltages of 2.3 V to 5.5 V. The ADP2118 requires minimal external parts and provides a high efficiency solution with its integrated power switch, synchronous rectifier, and internal compensation. Other key features include undervoltage lockout (UVLO), integrated soft start to limit inrush current at startup, overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown (TSD).
