3 Description
The TPSM842xx power module is an easy-to-use
integrated power solution that combines a 1.5-A
DC/DC converter with power MOSFETs, an inductor,
and passives into a 3-pin, through-hole package. This
total power solution requires adding only input and
output capacitors and eliminates the loop
compensation and magnetics part selection from the
design process.
The standard TO-220 pin-out allows a much
improved replacement of linear regulators packaged
in this industry standard footprint. The TPSM842xx
devices provide much higher efficiency without the
need of a heatsink.
