TPSM84205 (ACTIVE)

1.5A, 28V Input, 5V Output TO-220 Power Module

 

Recommended alternative parts

  • TPS709  -  30V Wide Input, Ultra-Low IQ LDO with Reverse Current Protection
  • TPS7A16  -  60V Low IQ LDO with Enable and Power Good
  • TPS7A39  -  Dual Positive-Negative LDO with +/- 33V operation

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.
