DEMO MANUAL DC2372A

Quick start proceDure

This Demonstration circuit 2372A can be evaluated using
the setup shown in Figure 1.
1. Connect voltmeters to V
tions for jumper JP1 (ON) and JP2 (PWM).
2. With input power supply set for 0V, connect the supply
to V and GND terminals.

3. Slowly increase the input power supply to 1.8V. Observe
output voltage and verify that it meets the specifications
in the Performance Summary table.

4. Connect a suitable load resistor or active load to the
output terminals and verify that it meets specifications
in the Performance Summary table.
5. Use a scope to monitor the output voltage ripple in
both PWM mode and Burst Mode operation by moving
the mode jumper JP2 to the appropriate position. See
Figure 4 for correct method for evaluating output ripple.
6. Note: If jumper JP2 is set for Burst Mode operation,
maximum output current is limited to approximately
100mA at 5V .
