Accelerate Your USB Power Delivery Battery Charger Designs
Migrating from a 1S to a 2S battery increases the capacity without increasing the charging current. Since USB-C supports input voltages between 5 V and 20 V and 2S or 3S battery voltages fall somewhere in between, a buck-boost converter can help bridge the gap. See Figure 2 for a block diagram of a 2S battery-based application.
