Voltage Drop Compensation on the MC13783 Switchers Line
Application note detailing how to compensate for voltage drops in MC13783 PMIC switchers by placing PCB wire resistance inside the feedback loop to ensure voltage stability.
Overview
This application note provides a recommended configuration for the NXP MC13783 Power Management IC to compensate for voltage drops caused by PCB trace resistance. The document describes a layout strategy where the output capacitor is placed near the load and the PCB wire resistance is included inside the switcher's closed loop. This ensures the DC voltage is stabilized at the output side. Key recommendations include using a shielded feedback trace to the high-impedance SWxyFB pin to minimize interference and maintain switcher stability.
Use Cases
- Power management for mobile electronics
- Optimizing PCB layout for switching regulators
- Compensating for trace resistance in high-current power lines
- Designing stable power supplies with the MC13783 PMIC
