Abstract

The TPS546x24y family uses the VOSNS pin to sense output voltage for closed-loop regulation. Since the VOSNS pin is limited to 5.5V, applications requiring higher output voltages must use an external resistor divider to scale the feedback signal. This application note describes how to design the VOSNS resistor divider for output voltages exceeding 5.5V, the effects on telemetry, fault management, and design limitations.
