The Texas Instruments UCD3138064ARGCR is a highly integrated digital controller designed for isolated power supply applications. This device operates within a voltage range of 3V to 3.6V and consumes a maximum operating current of 105 mA. It is specified for operation across a wide temperature range, from -40°C to 125°C.
The controller is housed in a 64-VQFN (9x9 mm) exposed pad package, suitable for surface mounting. Key features include 64 kB of Program Flash memory and support for multiple feedback loops. The device offers advanced control capabilities such as configurable non-linear control, soft start/stop, and fast input voltage feed-forward.
Additional functionalities include hardware synchronous rectifier dead time optimization, an Error A/D Converter (EADC) with configurable resolution, and up to 8 high-resolution Digital Pulse Width Modulated (DPWM) outputs. The UCD3138064ARGCR supports various control modes including voltage, average current, and peak current mode control, as well as constant current and constant power operation. It also provides fault protection options with multiple analog and digital comparators.
