The charger can either be supplied by a USB port on pin USB or by a dc voltage from a wall adapter connected to pin AC.
Three highly efficient 2.
25MHz step-down converters are targeted at providing the core voltage, memory and I/O voltage in a processor based system.
The step-down converters enter a low power mode at light load for maximum efficiency across the widest possible range of load currents.
For low noise applications the devices can be forced into fixed frequency PWM using the I2C interface.
The step-down con...
