Description
The ZY1015 is an intelligent, fully programmable step-down point-of-load DC-DC module integrating digital power
conversion and intelligent power management. The ZY1015 completely eliminates the need for external
components for sequencing, tracking, protection, monitoring, and reporting. Performance parameters of the
ZY1015 are programmable by pin strapping and external resistor and capacitor and can be changed by a user at
any time during product development and service without a need for a communication bus.
