Description for the TPSM82866A
The TPSM8286xA device family consists of 4A and 6A step-down converter power modules designed for small solution size and high efficiency. The power modules integrate a synchronous step-down converter and an inductor to simplify design, reduce external components, and save PCB area. The low-profile and compact solution is designed for automated assembly by standard surface mount equipment. Tight output voltage accuracy, even with small output capacitors, is achieved though the DCS-Control architecture and the excellent load transient performance. At medium-to-heavy loads, the converter operates in PWM mode and automatically enters power save mode operation at light load to maintain high efficiency over the entire load current range. The devices can also be forced in PWM mode operation for the smallest output voltage ripple. The EN and PG pins, which support sequencing configurations, bring a flexible system design. An integrated soft start reduces the inrush current required from the input supply. The RDJ package supports thin designs with 1.4mm height.
