envelope. This is typical for small-form-factor PCs or "All-in-One" (AIO) desktops like the Inspiron 3477
Most 35W power modules, including the IPKBLSR variant, follow a standard linear or switching topology. According to Electric Circuit Studio , a standard power supply schematic is broken into four primary stages: ipkblsr 35w schematic
Similar in power profile to the Apple 35W Dual USB-C Adapter . envelope

The first stage takes the universal AC input (90-305VAC). Instead of feeding this directly into a transformer, the schematic routes it through a PFC boost circuit. This stage steps the voltage up to a stable internal DC bus (typically around 380V–400V).
— meaning instead of a diode on the output, there’s a second MOSFET driven by the controller. This hits 94%+ efficiency, critical for 35W in a tiny enclosure.
