The 3MHz PWM switching frequency allows the use of very small external inductors and capacitors. Both step-down converters can enter skip mode under light load conditions to further improve the efficiency and maximize the battery life. For noise sensitive applications, they can also be programmed through I2C interface to operate in forced PWM mode regardless of the load current condition. The I2C interface supports on-the-fly slew rate control of the output voltage from 0.825V to 3.6V at 25mV/step size for dynamic power saving. Each step-down converter can supply up to 1.5A load current. The default output voltage can be set from 0.8V to VIN using external feedback resistors on the adjustable version, or the ISL9305H can be ordered in factory pre-set power-up default voltages in increments of 100mV from 0.9V to 3.6V.
