UCD3138RGCR Description

Short technical summary and product information.

The UCD3138RGCR from Texas Instruments is a highly integrated digital controller designed for isolated power applications. This device offers advanced control capabilities for power management systems.

 

Key electrical specifications include an operating voltage range of 3V to 3.6V and a maximum current rating of 100 mA. The controller operates across a wide temperature range, from -40°C to 125°C, making it suitable for demanding environments. It features up to 8 high-resolution Digital Pulse Width Modulated (DPWM) outputs with 250-ps pulse width resolution and 4-ns frequency and phase resolution.

 

This digital power controller supports various control modes, including voltage mode, average current mode, peak current mode, constant current, and constant power. It also incorporates features for high efficiency and light load management, such as burst mode and ideal diode emulation. The device is housed in a 64-VQFN (9x9 mm) exposed pad package, designed for surface mounting.

 

The UCD3138RGCR is well-suited for applications requiring precise digital control of isolated power supplies, including AC/DC switching regulators and DC/DC converters.
