DC/DC Buck Regulator
Overview
Inductor-based buck switching regulator generating the SoC internal voltage supply from rails, lithium coin cell or 2xAA batteries.
Key Features
- 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
