Test Summary

2.3.2.6 Switch to Boost Mode

1. Turn off and disconnect PS#1

2. If the constant voltage load connected from BAT+ to GND is not a four-quadrant supply (sources

current) remove the load and use the power source disconnected in step one, set to 3.7 V and 2 A

current limit and connect between BAT+ and GND

3. Apply 10 Ω (5 W or greater) across J5 (PMID(+) to GND(–)

4. Uncheck the OTG Low box in the GUI

5. Select OTG in the Configuration drop-down window

6. Verify V

PMID

to GND on J5 is between 4.9 V and 5.3 V

7. Verify scope measurement (See Figure 6)

C1 (AC coupled 20 mV/div): Vac_PMID (TP20 to GND) – Ripple excluding high frequency spikes

C2 (5 V/div): Vdc_SW (TP2) - Frequency between 1.2 MHz and 1.7 MHz, Duty cycle between 67%

and 74%
