The UCD3138RHAR from Texas Instruments is a highly integrated digital controller designed for isolated power applications. This device provides digital control for up to 3 independent feedback loops, enabling precise power management.
Key electrical specifications include a switching frequency of up to 2MHz, a pulse width resolution of 250ps, and frequency/phase resolution of 4ns. It features an Error Analog-to-Digital Converter (EADC) with configurable resolution as small as 1mV/LSB and up to 8x oversampling. The controller also boasts up to 8 high-resolution Digital Pulse Width Modulated (DPWM) outputs.
Designed for flexibility, the UCD3138RHAR supports various feedback control methods such as Voltage Mode, Average Current Mode, and Peak Current Mode Control. It also offers configurable modulation methods including Frequency Modulation, Phase Shift Modulation, and Pulse Width Modulation. The device operates within a voltage range of 3V to 3.6V and has an operating current of 100mA.
Packaged in a 40-VQFN (6x6mm) surface-mount package, the UCD3138RHAR is suitable for space-constrained designs. Its operating temperature range is -40°C to 125°C, making it robust for various environmental conditions.
