7.7 SMPS Voltage Regulators

The buck controllers integrate gate drivers for external power stages with programmable current limit (set by an external resistor at ILIMx pin), which allows for optimal selection of external passive components based on the desired system load. The buck converters include integrated power stage and require a minimum number of pins for power input, inductor, and output voltage feedback input. Combined with high-frequency switching, all these features allow use of inductors in small form factor, thus reducing total-system cost and size.

BUCK1–BUCK6 have selectable auto- and forced-pulse width modulation (PWM) mode through the BUCKx_MODE bit in the BUCKxCTRL register. In default auto mode, the VR automatically switches between PWM and pulsed frequency modulation (PFM) depending on the output load to maximize efficiency.

All controllers and converters can be used with the default VOUT or can have their voltage dynamically changed at any time. This means that the rails can be default programmed for any available VOUT by OTP programming at the factory, so the device starts up with the default voltage, or during operation the rail can be configured by I2C to another operating VOUT while the rail is enable or disabled. There are two step sizes or ranges available for VOUT selection : 10-mV and 25-mV steps. The step-size range must be selected prior to use and must be programmed in the OTP at the factory. It is not subject to change during operation.

For the 10-mV step-size range VOUT options, see Table 7-22. For the 25-mV step-size range VOUT options, see Table 7-23.
