ADP1873 Evaluation Board

Product Details

This describes the evaluation board hardware for the ADP1872/ADP1873 PWM buck controllers. The evaluation boards can be used to evaluate the ADP1872 or ADP1873 and application circuits using these ICs without requiring any additional software.

The ADP1872/ADP1873 evaluation boards employ a power input voltage (VIN) that ranges between 2.75 V and 20 V and a bias supply voltage (VDD) that ranges between 2.75 V and 5.5 V. Both inputs can be tied together for application input voltage conditions equal to or less than 5.5 V. The evaluation boards are available in two fixed-output voltage options (VOUT = 1.8 V and VOUT = 3.3 V), as well as in a 300 kHz, 600 kHz, or 1 MHz switching frequency (test trimmed in production). The ADP1872/ADP1873 evaluation boards offer an output accuracy of 2% over the full temperature range and provide a high input voltage (VIN ± 10%) and a full-scale load current up to 15 A.

The ADP1872/ADP1873 are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current limit protection by using a constant on-time, pseudo-fixed frequency with a programmable current-sense gain, current-control scheme. The ADP1873 is the power saving mode (PSM) version of the device and is capable of pulse skipping to maintain output regulation while achieving improved system efficiency at light loads. Both devices are available in a small, 10-lead MSOP package and can operate over the −40°C to +125°C temperature range.
