The ADP2164-EVALZ is an evaluation board for the ADP2164 step-down regulator. The ADP2164 is a synchronous, step-down dc to dc regulator in a compact, 4mm × 4mm LFCSP package. The ADP2164 requires minimal external components to provide a high efficiency solution with integrated power switch, synchronous rectifier and internal compensation. The ADP2164 evaluation board provides an easy way to evaluate the device. The ADP2164 evaluation board is fully assembled and tested. The ADP2164 integrates a pair of low on-resistance P channel and N channel internal Mosfet's to maximize efficiency and minimize external component count. The 100% duty cycle operation allows low dropout voltage at 4A output current. The high, 1.2MHz PWM switching frequency allows the use of small external components and the SYNC input enables multiple ICs to synchronise out of phase to reduce ripple and eliminate beat frequencies.
