IC DGTL PWR CTRLR 40VQFN
Texas Instruments UCD3138RJAR is a highly integrated digital power controller designed for isolated power conversion, supporting AC-DC and isolated DC-DC power supply applications. The device integrates programmable digital control functions, multiple feedback loops and high-resolution DPWM outputs for flexible power management.
Control Performance: UCD3138RJAR supports up to 3 independent digital feedback loops with dedicated PID-based control hardware, an EADC and up to 8 high-resolution DPWM outputs, with pulse-width resolution down to 250 ps, enabling precise regulation and fast dynamic response.
Features: UCD3138RJAR integrates a 31.25-MHz 32-bit ARM7TDMI-S processor, 12-bit general-purpose ADC, I²C/PMBus communication and multiple power-management peripherals, supporting functions such as soft start, current sharing, synchronous rectification, burst mode and input-voltage feed-forward.
Package & Application: UCD3138RJAR is a Texas Instruments digital power supply controller in a 40-pin VQFN (RJA) package, with a -40°C to +125°C** operating temperature range, suitable for compact AC-DC and isolated DC-DC power conversion designs. Note that the supplied “VQFN-64” information does not match TI’s current official specification for UCD3138RJAR; TI lists the 64-pin VQFN variant as UCD3138RGCR/RGCT.
