Inductor-based buck switching regulator generating the SoC internal voltage supply from rails, lithium coin cell or 2xAA batteries.
Key Benefits
- High efficiency buck regulator (up to 95% in peak), thanks to dual mode (dm) controller
- Pulse Frequency Modulation (PFM) mode at low load and Pulse With Modulation (PWM) mode at high load.
- Low Bill-Of-Material: fully integrated feedback and active compensation loop do not require additional external passive components.
- Behavioral models: ease integration in SoC and optimized Power Management Network (PMNet) by verifying mode transitions as well as noise propagation

Technical information
- Technology: TSMC 40 uLP eFlash
- Add-ons:
- Over-voltage protection module (OPM) required for 2.7 to 5.5 V and 1.9 to 4.4 V input voltage range. The OPM enables over-voltage operation (up to 5.5 V) while using standard process 3.3 V devices.
