Assuming “ipkblsr 35w” is a buck-boost converter for USB-C PPS:
[Input: 12V DC] ---[Fuse]---[KBL406 Bridge]---+---[100µF 50V]---[SW pin: IPK IC]---[Inductor 22µH]---[Output Cap]---[USB-C Port]

+---[GND]---------------------------------[Current sense resistor 10mΩ]
The “SR” in the name suggests synchronous rectification — 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.

The term "IPKBLSR 35W" may cover different outputs. The schematic changes slightly based on voltage:
| Output Voltage | Transformer Turns Ratio | Feedback Resistors (R7/R8) | Output Cap Rating | | :--- | :--- | :--- | :--- | | 5V / 7A | 15:1 | 1k / 1k | 10V (use 16V) | | 12V / 2.9A | 6:1 | 10k / 2.4k | 16V (use 25V) | | 24V / 1.5A | 3:1 | 10k / 1.15k | 35V | Assuming “ipkblsr 35w” is a buck-boost converter for
Calculate your own feedback: Vout = 2.5V × (1 + R7/R8) where R7 is top resistor from Vout to REF, R8 is from REF to GND.

Note: “IPKBLsr 35W” appears to be an identifier that likely refers to a 35-watt power supply, amplifier module, or LED driver module model. Because the exact manufacturer or published datasheet for “IPKBLsr 35W” isn’t available in common references, this essay treats the label as a typical 35 W power-electronics module and explains likely schematic features, design considerations, troubleshooting tips, and how to interpret and work with such schematics. If you have an exact datasheet or image of the schematic, provide it for a precise analysis. The “SR” in the name suggests synchronous rectification
