Switched Capacitor Chargers
11.7HMI’s switched capacitor chargers are the best-known solution to charge a battery with 2C-4C in a short time. The dual-phase topology provides the smallest ripple voltage with a high-current charge. The products feature four different operation modes, forward 1:1 (bypass), 2:1 CP, reverse 1:2 CP, and 1:1 (bypass) supporting all application conditions. HMI switched capacitor charger ICs are the best-known technology to charge the batteries safely and fast working with USB PD adapter.
