ADP1882-0.6-EVALZ

ANALOG DEVICES  ADP1882-0.6-EVALZ  评估板, 强制PWM, 600KHZ

The is an evaluation boards to test the ADP1882 switching controller at 600kHz switching frequency. The ADP1882 is a 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 limit, current control scheme. In addition, this devices offer optimum performance at low duty cycles by using valley current mode control architecture. This allows the ADP1882 to drive all N channel power stages to regulate output voltages as low as 0.8V. An internally fixed soft start period is included to limit input in rush current from the input supply during startup and to provide reverse current protection during soft start for a pre charged output.
