GENERAL DESCRIPTION

The ADP1055 is a flexible, feature-rich digital secondary side controller that targets ac-to-dc and isolated dc-to-dc secondary side applications. The ADP1055 is optimized for minimal component count, maximum flexibility, and minimum design time. Features include differential remote voltage sense, primary and secondary side current sense, pulse-width modulation (PWM) generation, frequency synchronization, redundant OVP, and current sharing. The control loop digital filter and compensation terms are integrated and can be programmed over the PMBus? interface. Programmable protection features include overcurrent (OCP), overvoltage (OVP) limiting, undervoltage lockout (UVLO), and external overtemperature (OTP).
