Module type: DC automatic voltage rise and fall power supply
Starting voltage: 2.8V (After starting, the module can output positive E normally within an input voltage of 2V-9V)
Input voltage: 2V -16V
Output voltage: 2.5V -9V
Output current: 2A (MAX). The output MAX current at different voltages can refer to "Table 1"
Working mode: PWM/PFM
Output ripple: 10mV (9V), 8mV (5V), 8mV (3 3V)
(Note that the ripple data above is for reference only and is not included in the sample's no-load test.)
There may be slight differences between the same chips, and the carrier ripple can refer to "Table 1"
Adjustment method: Jumper pad selection
