User's Guide SLIU006 – December 2011 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). Table 1.
Setup www.ti.com JP3 – LPM is the jumper used to enable Low Power Mode (LPM). The jumper allows LPM to be enabled or disabled. The device will operate in Normal mode when LPM is disabled. 0 0 1 1 LPM LPM disabled enabled Figure 2. Low Power Mode Jumper Settings JP4 – Enable is the jumper used to enable the converter. The converter is enabled when the Enable is high and disabled when low. The jumper placement allows the converter to be enabled or disabled.
Board Layout www.ti.com 2.3 Operation For proper operation of the TPIC74101, JP1, JP2, JP3, JP4, JP5, and JP6 should be properly configured. The recommended setting, using shorting blocks: JP1 and JP2 to Fast JP3 to Enabled JP4 to Enabled JP5 to Enabled, if 5Vg is used JP6 to Shorted In this configuration, the device powers up when power is applied. JP1, JP2 SCR0, SCR1 select how switch pin slew rate is set: slow, medium-slow, medium-fast, or fast.
