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.
