ADP1055-EVALZ屬于開發(fā)板套件編程器的評估演示板及套件。由亞德諾半導體技術有限公司制造生產(chǎn)的ADP1055-EVALZ評估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗證的實施環(huán)境中評估某些重點器件的性能或特性。評估方法通常有完善的文檔說明，并且視乎具體情況由評估軟件提供支持。產(chǎn)品通常由印刷電路板組成，板上已裝有重點器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對于數(shù)量特別多或類別獨特的器件類別(如 ADC、DAC 和開關模式電源)，評估平臺可組合為一個單獨的產(chǎn)品系列。

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).
