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).
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 PMBus provides access to the many moni-toring and system test functions. The ADP1055 is available in a 32-lead LFCSP and operates from a single 3.3 V supply.
Applications
- Isolated dc-to-dc power supplies and modules
- Redundant power supply systems
