The Texas Instruments UCD3138RJAR is a highly integrated digital controller designed for isolated power applications. This device provides digital control for up to 3 independent feedback loops, featuring a dedicated PID-based hardware 2-Pole/2-Zero configurable nonlinear control.
Key electrical specifications include an operating voltage range of 3V to 3.6V and a current consumption of 100 mA. It boasts up to 8 high-resolution Digital Pulse Width Modulated (DPWM) outputs with 250-ps pulse width resolution and 4-ns frequency/phase resolution. The controller supports a switching frequency of up to 2 MHz and includes 7 high-speed analog comparators for fault protection.
The UCD3138RJAR is housed in a 40-VQFN (6x6) package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C, making it robust for various environmental conditions. The device also offers features for high efficiency and light load management, such as burst mode and ideal diode emulation.
This digital power controller is well-suited for applications requiring precise and efficient power management, including AC/DC switching regulators and DC/DC power modules. Its integrated fault protection and configurable control methods enhance system reliability and performance.
