Texas Instruments TPS821x0 Step-Down Converter Modules
Texas Instruments TPS821x0 Step-Down Converter Modules are 17V input 1A (TPS82150), 2A (TPS52140), or 3A (TPS82130) step-down converter MicroSiP™ power modules optimized for small solution size and high efficiency. Each module integrates a synchronous step-down converter and an inductor to simplify design, reduce external components and save PCB area. This low-profile, compact solution is suitable for automated assembly by standard surface mount equipment. The converter maximizes efficiency by operating in PWM mode with a nominal switching frequency of 2.0MHz and automatically enters Power Save Mode operation at light load currents. In Power Save Mode, the device operates with typically 20µA quiescent current. The device uses the Texas Instruments DCS-Control topology to achieve excellent load transient performance and accurate output voltage regulation.
