ADP1055 제품 세부 정보

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).

FEATURES
    −40°C to +125°C operation
    PMBus Revision 1.2 compliant with PEC and extended manufacturer specific commands
    32-bit password protection with command masking
    64 address selections (16 base addresses, expandable to 64)
    6 PWM control signals, 625 ps resolution
    Frequency from 48 kHz to 1 MHz
    Duty cycle double update rate
    Digital control loop (PID + additional pole or zero configurability)
    Programmable loop filters (CCM, DCM, low/normal temperature)
    Fast line voltage feedforward
    Adaptive dead time compensation for improved efficiency
    Remote voltage sense
    Redundant programmable OVP
    Current sense Primary side cycle-by-cycle fast protection Secondary side cycle-by-cycle fast overcurrent protection Secondary side averaged reverse current protection using diode emulation mode with fixed debounce
    Synchronous rectifier control for improved efficiency in light load mode
    Nonlinear gain for faster transient response from DCM to CCM
    Frequency synchronization
    Soft start and soft stop functionality
    Average and peak constant current mode
    External PN junction temperature sensing
    4 GPIOs (2 GPIOs configurable as active clamp snubber PWMs)
    Extended black box data recorder for fault recording
    User trimming on input and output voltages and currents
    Digital current sharing

APPLICATIONS
    Isolated dc-to-dc power supplies and modules
    Redundant power supply systems
