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.

JP6 – Bypass

 is the jumper used to bypass the low pass filter inductor on the power supply input to the device. 

This allows the user to remove the filter from the circuit. The jumper placement allows the inductor to be active or 
shorted.

2.2 Setup

The input voltage range for the converter is 1.5 V to 40 V. The input voltage must be at least 5 V during start up.

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
