ADP1046是一款靈活的數字副邊控制器，設計用于AC-DC和隔離DC-DC副邊應用。ADP1046與ADP1043A引腳兼容，具有一些性能改進和新特性，包括電壓前饋、改進環路響應，以及可編程死區控制，以實現最高效率。
　　ADP1046還為實現最低元件數量、最大靈活性和最少設計時間進行了優化。具體特性包括本地和遠程電壓檢測、原邊和副邊電流檢測、數字脈寬調制（PWM）產生、均流和冗余OrFET控制。控制環路數字濾波器和補償功能已集成至該器件，可通過I2C 接口編程。可編程保護功能包括過流保護（OCP）、過壓保護（OVP）、欠壓閉鎖（UVLO）和過溫保護（OTP）。
　　內置的EEPROM允許對集成的環路濾波器、PWM信號時序、浪涌電流和軟啟動時序進行廣泛的編程。通過內置校驗和及可編程保護電路，可靠性得以提高。
　　全面的GUI簡化了環路濾波器特性的設計和安全特性的編程。工業標準I2C總線可用于訪問許多監控和系統測試功能。
　　ADP1046提供32引腳LFCSP封裝，采用3.3 V單電源供電。
　　The ADP1046 is a flexible， digital secondary side controller designed for ac-to-dc and isolated dc-to-dc secondary side applications. The ADP1046 is pin-compatible with the ADP1043A and offers several enhancements and new features， including voltage feedforward， improved loop response， and programmable dead time control to maximize efficiency.
　　The ADP1046 is optimized for minimal component count， maximum flexibility， and minimum design time. Features include local and remote voltage sense， primary and secondary side current sense， digital pulse-width modulation （PWM） generation， current sharing， and redundant OrFET control. The control loop digital filter and compensation terms are integrated and can be programmed over the I2C interface. Programmable protection features include overcurrent protection （OCP）， over-voltage protection （OVP）， undervoltage lockout （UVLO）， and overtemperature protection （OTP）。
　　The built-in EEPROM provides extensive programming of the integrated loop filter， PWM signal timing， inrush current， and soft start timing and sequencing. Reliability is improved through a built-in checksum and programmable protection circuits.
　　A comprehensive GUI is provided for easy design of loop filter characteristics and programming of the safety features. The industry-standard I2C bus provides access to the many monitoring and system test functions.The ADP1046 is available in a 32-lead LFCSP and operates from a single 3.3 V supply.
