UCD3138064RGZR Description

Short technical summary and product information.

The UCD3138064RGZR from Texas Instruments is a digital power controller designed for isolated power supplies. It integrates a high-performance 31.25 MHz, 32-bit ARM7TDMI-S processor with 64 kB of program Flash memory, 2 kB of data Flash with ECC, and 4 kB of data RAM.

Key features include phase shift modulation, PWM control, high efficiency, and light load management. It supports burst mode, ideal diode emulation, and synchronous rectifier soft on/off. The device offers primary side voltage sensing and flux/phase current balancing capabilities. It also includes a rich set of fault protection options, multiple ADCs for voltage and current sensing, and up to 8 high-resolution DPWM outputs.

This controller is suitable for applications such as power supplies, telecom rectifiers, and isolated DC-DC modules. It operates within a voltage range of 3V to 3.6V and has an operating temperature range of -40°C to 125°C. The UCD3138064RGZR is provided in a 48-VQFN (7x7) surface mount package with an exposed pad.

Additional communication ports compared to the UCD3138 include +1 SPI and +1 I2C. The device supports firmware updates without shutting down the power supply, offering flexibility in system design.
