TPIC74101EVM User's Guide
1 Introduction
The Texas Instruments TPIC74101EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the TPIC74101 Switch Mode Power Supply – Buck Regulator. The EVM contains one
DC / DC converter (See Table 1).

2 Setup
This section describes the jumpers and connectors on the EVM as well and how to properly connect, set
up, and use the TPIC74101EVM.
2.1 Input/Output Connector Description
J1 – VBAT is the power input terminal for the converter. The terminal provides power (Vbat).
J2 – GND is the ground terminal for the EVM.
J3 – 5Vg is the power output terminal for the 5Vg regulator output.
J4 – VOUT is the regulated output voltage for the converter.
J5 – GND is a ground terminal for the EVM.
JP1, JP2 – SCR1, SCR0 are jumpers used to set the slew rate of the switching transistor for the L1
terminal switch pin. Jumpers allow the slew rate to be set to four set points.
