Description:

The TPSM8282x device family comprises 1A, 2A, and 3A step-down converter MicroSiP™ power modules optimized for small solution size and high efficiency. The power module integrates a synchronous step-down converter and an inductor to simplify design, reduce external components, and save printed circuit board (PCB) area. The TPSM8282x features two variants. The first variant automatically enters power save mode to maintain high efficiency at ultra-light loads, extending system battery run-time. The second variant, TPSM8282xA, enables forced PWM operation to maintain continuous conduction mode across all currents, minimizing the output voltage ripple. In PWM mode, the converter operates at a nominal switching frequency of 4MHz. In power save mode, the device features a typical operating quiescent current of 4µA. By utilizing the DCS-Control topology, the device achieves excellent load transient performance and precise output voltage regulation. The device's EN and PG pins support sequencing configurations, enabling flexible system design. The integrated soft-start feature reduces the inrush current required from the input power supply. Thermal protection and(hiccup) short-circuit protection make the solution robust and reliable.
