Description
The UCD3138064 is a digital power supply controller from Texas Instruments offering superior levels of
integration and performance in a single chip solution. The UCD3138064, in comparison to Texas
Instruments UCD3138 digital power controller (Section
3),
offers 64 kB of program Flash memory (vs 32
kB in UCD3138) and additional options for communication such as SPI and a second I
2
C port. The
availability of 64 kB of program Flash memory in 2-32 kB banks, enables the designers to implement dual
images of firmware (e.g. one main image + one back-up image) in the device and the flexibility to execute
from either of the banks using appropriate algorithms. It also creates the unique opportunity for the
processor to load a new program and subsequently execute that program without interrupting power
delivery. This feature allows the end user to add new features to the power supply in the field while
eliminating any down-time required to load the new program.
The flexible nature of the UCD3138064 makes it suitable for a wide variety of power conversion
applications. In addition, multiple peripherals inside the device have been specifically optimized to
enhance the performance of AC/DC and isolated DC/DC applications and reduce the solution component
count in the IT and network infrastructure space. The UCD3138064 is a fully programmable solution
offering customers complete control of their application, along with ample ability to differentiate their
solution. At the same time, TI is committed to simplifying our customer’s development effort through
offering best in class development tools, including application firmware, Code Composer Studio
TM
software development environment, and TI’s Fusion Power Development GUI which enables customers to
configure and monitor key system parameters.
At the core of the UCD3138064 controller are the Digital Power Peripherals (DPP). Each DPP implements
a high speed digital control loop consisting of a dedicated Error Analog to Digital Converter (EADC), a PID
based 2 pole - 2 zero digital compensator and DPWM outputs with 250ps pulse width resolution. The
device also contains a 12-bit, 267 ksps general purpose ADC with up to 14 channels, timers, interrupt
control, PMBus, I
2
C, SPI and UART communications ports. The device is based on a 32-bit ARM7TDMI-S
RISC microcontroller that performs real-time monitoring, configures peripherals and manages
communications. The ARM microcontroller executes its program out of programmable flash memory as
well as on chip RAM and ROM.
In addition to the DPP, specific power management peripherals have been added to enable high efficiency
across the entire operating range, high integration for increased power density, reliability, and lowest
overall system cost and high flexibility with support for the widest number of control schemes and
topologies. Such peripherals include: light load burst mode, synchronous rectification, LLC and phase
shifted full bridge mode switching, input voltage feed forward, copper trace current sense, ideal diode
emulation, constant current constant power control, synchronous rectification soft on and off, peak current
mode control, flux balancing, secondary side input voltage sensing, high resolution current sharing,
hardware configurable soft start with pre bias, as well as several other features. Topology support has
been optimized for voltage mode and peak current mode controlled phase shifted full bridge, single and
dual phase PFC, bridgeless PFC, hard switched full bridge and half bridge, and LLC half bridge and full
bridge.
