3 Description

The TPSM8286xx device family consists of 4A and

6A step-down converter power modules designed for

small solution size and high efficiency. The power

modules uses TI's MagPack technology to integrate

a synchronous step-down converter and an inductor

to simplify design, reduce external components, and

save PCB area. The compact design is excellent

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

I2C interface provides an effective way of adjusting

the output voltage, setting the VOUT ramp rate when

transitioning to a new setpoint or reading status

information like thermal warning or current limit flags.

An integrated soft start reduces the inrush current

required from the input supply. Overtemperature

protection and hiccup short-circuit protection deliver

a robust and reliable design.
