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.

Pin Functions

PIN I/O DESCRIPTION
NAME NO.
GND 2 Ground. This is the return current path for the power stage of the device. Connect this pin to the bypass capacitors associated with VIN and VOUT.
VIN 1 I Input Voltage. This pin supplies voltage to the control circuitry and power switches of the converter. Connect external bypass capacitors between this pin and GND.
VOUT 3 O Output Voltage. This pin is connected to the internal output inductor. Connect this pin to the output load and connect external bypass capacitors between this pin and GND.
