ADP1046是一款灵活的数字副边控制器，设计用于AC-DC和隔离DC-DC副边应用。ADP1046与ADP1043A引脚兼容，具有一些性能改进和新特性，包括电压前馈、改进环路响应，以及可编程死区控制，以实现最高效率。
ADP1046还为实现最低元件数量、最大灵活性和最少设计时间进行了优化。具体特性包括本地和远程电压检测、原边和副边电流检测、数字脉宽调制（PWM）产生、均流和冗余OrFET控制。控制环路数字滤波器和补偿功能已集成至该器件，可通过I2C 接口编程。可编程保护功能包括过流保护（OCP）、过压保护（OVP）、欠压闭锁（UVLO）和过温保护（OTP）。
内置的EEPROM允许对集成的环路滤波器、PWM信号时序、浪涌电流和软启动时序进行广泛的编程。通过内置校验和及可编程保护电路，可靠性得以提高。
全面的GUI简化了环路滤波器特性的设计和安全特性的编程。工业标准I2C总线可用于访问许多监控和系统测试功能。
ADP1046提供32引脚LFCSP封装，采用3.3 V单电源供电。
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.
