The UCD3138RJAT from Texas Instruments is a highly integrated digital controller designed for isolated power applications. This device features digital control of up to 3 independent feedback loops and provides 8 high-resolution Digital Pulse Width Modulated (DPWM) outputs with 250-ps pulse width resolution.
Key electrical specifications include an operating voltage range of 3V to 3.6V and an operating current of 100 mA. The controller incorporates a 16 MHz Error Analog-to-Digital Converter (EADC) with configurable resolution as low as 1mV/LSB and a 14-bit effective Digital-to-Analog Converter (DAC). It supports up to 2-MHz switching frequency and offers configurable feedback control modes such as Voltage Mode, Average Current Mode, and Peak Current Mode.
Designed for demanding power applications, the UCD3138RJAT operates within a temperature range of -40°C to 125°C. It is available in a 40-VQFN (6x6) package, suitable for surface mount applications. The controller includes features for high efficiency and light load management, such as Burst Mode and Ideal Diode Emulation, along with robust fault protection options including 7 high-speed analog comparators and cycle-by-cycle current limiting.
