10 Power Supply Recommendations

For proper operation of bqSWITCHER™, VCC and IN (tied together) must be from 4.35 V to 16 V. Power limit for the input supply must be greater than the maximum power required for charging the battery (plus any additional load on the output of the switch-mode converter).
