Problem
Step up a battery pack to a regulated higher voltage with high efficiency and robust transient response for motor loads.
Approach
- Set electrical requirements; inductor/diode/MOSFET sizing and switch-node loss estimates.
- LTspice sims: duty cycle, ripple, loop stability; compensation network design.
- PCB layout for tight current loops, Kelvin sensing, and thermal spreading.
- MCU PWM control (soft-start, OCP/OVP), test plan for line/load/thermal.
Impact
- Stable regulation across expected load range.
- Thermal performance verified on bench; reusable power stage for future robots.
Tech
- Control: current-mode, compensation, soft-start
- HW: MOSFET gate drive, sense resistors, thermal vias
- SW: Embedded control for PWM & protections
