Introduction; Scope Of This Document; A Guide To Other Documentation For All Members Of Ucd3138 Family Of Products - Texas Instruments UCD3138 Technical Reference Manual

UCD3138 is a digital power supply controller from Texas Instruments offering superior levels of integration
and performance in a single chip solution targeting high-performance isolated power supply applications.
At its core are the digital control loop peripherals, also known as Digital Power Peripherals (DPP) that are
used for controlling the high-speed voltage/current loops, and a ARM7TDMI-S microcontroller (32-bit,
31.25MHz) that performs real-time monitoring, communication and configuration of peripherals. Each DPP
is capable of implementing a high speed digital control loop by employing a dedicated, high-speed Error
Analog to Digital Converter (EADC), a PID based 2 pole–2 zero digital compensator and digital pulse
width modulator (DPWM) outputs with 250-ps pulse width resolution. The device also contains 12-bit,
267ksps general purpose ADC with up to 14 channels, timers, interrupt control, JTAG debug and PMBus
& UART communications ports. In terms of memory, UCD3138 offers 32KB of program flash, 2kB of data
flash, 4KB RAM and 4KB of ROM.
