Test Procedure:
1. Connect the test setup as shown above.
2. JP1 = OFF → Auto Mode
3. JP2 = OFF → Enable the device
4. Apply an input voltage, VIN = VSET + 1.0 V across T1 and T2.
5. Apply 100 mA loading from the electronic load after power up the demo board.
6. Check IIN, VOUT, and output ripple. It should match the desired results as shown below in Table 2.
Table 2: Desired Results IIN ≈ 80 mA to 83.3 mA
VOUT ≈2.46 V to 2.54 V For 2.5V devices,
VRIPPLE ≈ 10 mVP-P
IIN ≈ 81.6 mA to 83.4 mA VOUT ≈ 2.69 V to 2.72 V For 2.7V devices,
VRIPPLE ≈ 10 mVP-P
IIN ≈ 83.2 mA to 86 mA VOUT ≈ 2.98 V to 3.03 V For 3.0V devices,
VRIPPLE ≈ 11 mVP-P
IIN ≈ 83.42 mA to 87 mA VOUT ≈ 3.26 V to 3.33 V For 3.3V devices,
VRIPPLE ≈ 13 mVP-P
