Setup and Test Results www.ti.com
The output voltages reach their respective regulation voltages per Table 1 after the appropriate soft-start
times and relative delays. Resistive or electronic loads can be attached to output J2 for Vs and J3 for
Vlogic. Only resistive loads can be attached to outputs J4 for VGH and J5 for VGL. Exceeding an output
load specified in Table 1 results in the output voltage falling out of regulation.
Use EN1 (J6) to turn on the buck converter (VLOGIC) and negative charge pump (VGL). EN2 is used to
turn on the boost converter (Vs) and positive charge pump (VGH). With EN2 (J7) set to the on position,
EN1 controls on/off for all voltages.
