Highly Integrated Digital Controller for Isolated Power
Features
Benefits
? Digital Control of up to 3 Independent Feedback Loops
o Dedicated PID based hardware
o 2-pole/2-zero configurable
o Non-Linear Control
Provide the flexibility for creating compensation filters
for multiple topologies, create hardware nested loops,
and provide the ability to change filters cycle-by-cycle
depending on compensation requirements
? Up to 8 High Resolution Digital Pulse Width Modulated
(DPWM) Outputs
o 250ps Pulse Width Resolution
o 4ns Frequency Resolution
o 4ns Phase Resolution
o Adjustable Phase Shift Between Outputs
o Adjustable Dead-band Between Pairs
o Up to 2MHz Switching Frequency
High resolution allows for accurate loop regulation that
closely mimics that of analog control loops
? Configurable Feedback Control
o Voltage Mode
o Average Current Mode
o Peak Current Mode Control
o Constant Current
o Constant Power
Allows the controller to be used in all popular isolated
power topologies.
? Feature Rich Fault Protection Options
o 7 High Speed Analog Comparators
o Cycle-by-Cycle Current Limiting
o Programmable Fault Counting
o External Fault Inputs
o 4C10 Digital Comparators
Provides superior integrated fault protection that would
be difficult to perform in analog without adding
additional components - therefore provides a high level
of integration along with this protection.
Applications
? 14 channel, 12 bit, 267 ksps General Purpose ADC with
integrated
• Servers and Telecom Rectifiers
o Programmable
averaging
• Merchant Power
ODMfilters
and OEM Customers
o Dual sample and hold
? Fully Programmable High-Performance 31.25MHz, 32-bit
ARM7TDMI-S Processor with I2C PMBus and 2 UART ports.
o 32 kByte (kB) Program Flash
o 2 kB Data Flash with ECC
o 4 kB Data RAM
o 4 kB Boot ROM Enables Firmware Boot-Load in the Field

control and/or fault monitoring and control.
Powerful MCU well known in the market allows easier
firmware programming. 32kB flash provides adequate
memory size for all propular isolated power topology
configuration as well as the flexibility to add
differentiation in firmware. PMBus and UARTs provide
compatible interface to other power controllers, system
