/PRNewswire/ -- Expanding its broad portfolio of analog and digital power management products, Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced a highly integrated and configurable digital power management controller with 64 kB of program Flash memory for AC/DC and isolated DC/DC power supplies. The UCD3138064 allows designers to implement firmware upgrades "on-the-fly" without shutting off the power supply, reducing server downtime compared to existing solutions.

TI is demonstrating this new digital power management controller in its booth #109 at
Applied Power Electronics Conference and Expo (APEC)
Long Beach, Calif.
The UCD3138064 employs a unique memory partitioning architecture that gives users the ability to simultaneously write to and execute from different portions of the on-chip memory and dynamically switch execution between the various firmware images using appropriate algorithms. This capability reduces downtime in servers and telecom infrastructure equipment.
Key features and benefits of the UCD3138064:
Award-winning digital power solutions
- 64-kB program Flash memory can support digital controller sockets in AC/DC power supplies that require greater than 32 kB of memory.
- Multiple system communication options, such as UART, PMBus™, I2C and serial peripheral interface (SPI), easily interface with multiple devices on the system, including peer controllers, power metering ASICs and external EEPROM memory.
- Supports all isolated power supply topologies, including single-phase, two-phase interleaved or bridgeless power factor correction; phase-shifted full-bridge; resonant LLC; and hard-switching full-bridge. This gives customers the flexibility to use the UCD3138064 in a variety of power designs, regardless of topology.
The UCD3138064 is a 64-kB addition to TI's award-winning
UCD3138 digital power controller
family. In addition to analog and digital power management solutions, TI offers MCU-optimized
microcontrollers that enable digital control in power supplies. For more information, visit:
Making digital power design easier
In addition to the
UCD3138064 control card evaluation module
, designers have easy access to several UCD3138-based development tools. This includes full-function, feature-rich evaluation modules such as
UCD3138 digital power factor correction pre-regulator
UCD3138 digital resonant LLC converter
UCD3138 hard switching bridge converter
evaluation modules, along with associated application firmware source code; development, such as
