The ADP1851-EVALZ is an evaluation board to evaluate the performance of ADP1851 DC to DC controller. The ADP1851 is a step down switching controller with integrated drivers for N channel synchronous power MOSFETs. The ADP1851 can be set to operate in pulse skip mode (PSM) for high efficiency under light load, or in PWM continuous conduction mode. In addition, the boost diode is integrated into the ADP1851, thus lowering the overall system cost and component count. This regulator includes externally adjustable soft start, output overvoltage protection, externally programmable current limit, power good output, and a programmable oscillator frequency that ranges from 200KHz to 1.5MHz. The switching frequency of the ADP1851 can be synchronized to an external clock signal applied to the SYNC input. The ADP1851 has the reference voltage accuracy of ±1%. This controller can be powered from a 2.75V to 20V supply.
