The ZY2120 is an intelligent, fully programmable
step-down point-of-load DC-DC module integrating digital power conversion and power management. The ZY2120 eliminates the need for external components for sequencing, tracking, protection, monitoring, and reporting. Performance parameters of the ZY2120 are programmable by
pinstrapping and an external resistor, and can be changed by the user at any time during product development and service without a need for a communication bus.
