Introduction

AI Translation

The ADP1046A is a flexible, digital secondary side controller designed for ac-to-dc and isolated dc-to-dc secondary side applications. The ADP1046A is pin-compatible with the ADP1043A and offers several enhancements and new features, including voltage feedforward and improved loop response to maximize efficiency. The ADP1046A 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), overvoltage 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 ADP1046A is available in a 32-lead LFCSP and operates from a single 3.3 V supply.
