11 / 80 page 3.3.37 Integrated DC-DC Converter (DC-DC) The DC-DC buck converter covers a wide range of load currents and provides high efficiency in energy modes EM0, EM1, EM2 and EM3. Patent-pending RF noise mitigation allows operation of the DC-DC converter without degrading radio sensitivity. The converter has three modes: low noise (LN), low power (LP), and bypass. Each operating mode transition is initiated by firmware and executed by an integrated hardware state machine, providing well-controlled transitions. Bypass mode may be entered when the input voltage is too low for efficient operation of the DC-DC converter. In Bypass mode, the DC-DC input supply is internally connected directly to its output through a low resistance switch. Bypass mode also supports in-rush current limiting to avoid dipping the input supply due to excessive current transients. Key Features: • Wide load range from sub-µA to 200 mA • High efficiency up to 90% • Low Noise (LN), Low Power (LP) and Bypass operating modes for high performance and low energy applications • Fast wakeup from LP to LN to support quick EM2 to EM0 transition • Low 50 nA quiescent current in LP mode to support micro-ampere range load currents • Optimized for integration with the on-board radio • Switching frequency programmable from 3 MHz to 8 MHz • RF noise mitigation mechanism • Supports wide range of passive part selection • External capacitor range from 1 µF to 10 µF with external 4.7 µH inductor • Protection features • Programmable sourcing and sinking current limits • Output short-circuit protection • Dead-time protection DVDD PFET2 LN Controller LP Controller VREGVDD PFET1 VREGSW 1.0uF 4.7uH NFET VREGVSS Bypass mode enable LN mode enable LP mode enable SW Logic PWM pulses CLim ZDet Figure 3.2.
