Our customer are using ADP1046A.
But maybe they will change to ADP1055.
What is the different between these two device?
I am reading datasheet now.
But I could not find anything other than the GPIO difference.
In general ADP1055 is a more recent controller with PMBus. The front page will tell you the complete feature set.
Common features for ADP1046A, ADP105x
• State machine based design facilitates time to market
• No software coding required
• On board EEPROM
• Supports all common PWM topologies
• PWM outputs + SR Adjustable dead time
• On board ADCs for telemetry
• Easy and intuitive GUI
• I2C communication
• Protection features like OVP, OCP, OTP
• Pulse skipping and other light load mode features
• Redundant OVP pin
• Advanced features like active balancing for prevention of transformer saturation
• Forward and Reverse current protection
• Droop and digital current sharing
• Compensation for soft start, DCM, and CCM conditions
• OrFET control
• Suited for hard-switched and resonant topologies
• Burst mode
• Frequency clamp
• Adjustable deadtime for SR ZCS operation
• ADP1046AW is automotive qualified
• PMBus compliant v1.2
• Advanced control loop using FLASH ADC for lowest output noise
• Double update rate for reduced phase loss and high bandwidth
• PMBus compliant, upto 1MHz operation
• Active clamp snubber for output rectifiers for lowest loss
• Soft stop functionality, blackbox, 4 GPIOs
• Fast feedforward update rate (1us)
• Compensation based on load and temperature
• Better Volt second balance feature
Note that there may be other features on ADP1046A or ADP1055 not listed here but it is a pretty comprehensive list.
Hope that helps.
