Buck Converter Simulation Setup

Please run a .op simulation focusing on the 3.3V rail using the provided RT8059 buck converter model.
Setup:
  • Inputs: VSOLAR = 6V, VUSB = 5V, VBAT = 3.7V (test each input separately)
  • Load: 1A resistive load on the 3.3V output
  • Use the RT8059 model (VIN LX FB EN GND) to step down from VBAT to 3.3V
Checks:
  1. Ensure the buck regulator provides a stable 3.3V across input scenarios
  2. Confirm only the active input supplies current; others draw ≈0A
Output:
  • Table: active input, VBAT, buck input, 3.3V output, input current
  • Graph: 3.3V output vs input source (USB, solar, battery)

General
Project
Simulator (Beta)
U1
The .OP results with a stubbed RT8059 model show essentially 0 V out and ≈0 A input for the 6 V case—this is expected because a DC steady‐state OP won’t engage the switching loop. To capture a regulated 3.3 V output you need a transient simulation including the internal PWM action and feedback dynamics.
Would you like me to:
  • Set up a transient (.TRAN) simulation to observe the 3.3 V regulation and input currents over time?
  • Or provide guidance on how to modify the .OP test to use a behavioral DC source model that approximates the closed-loop 3.3 V?
