You want a Buffer Summer Splitter design.

I created a plan to define the signal path, capture the electrical requirements, build the schematic, and prepare the PCB layout.
Since the plan is ready, click Start in the plan bar to begin.
If you want, I can also update the plan first with details like input/output count, signal type, voltage range, and bandwidth.

Set channel count

Add voltage details

Specify op-amp choice

Refine frequency target

Can you tell me about U1?

@copilot Can you tell me about U1?

U1 refers to the MT3608 High Efficiency 1.2MHz 2A Step Up Converter. Here are some key features and specifications:

It has an integrated 80m $\Omega$ Power MOSFET[9].
The input voltage range is 2V to 24V[9].
It operates at a fixed switching frequency of 1.2MHz[9].
The internal switch current limit is 4A[9].
The output voltage is adjustable and can go up to 28V[9].
It has an automatic pulse frequency modulation mode at light loads[9].
The efficiency can reach up to 97%[9].
It is available in a 6-Pin SOT23-6 Package[9].
The device includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload[9].
The absolute maximum ratings for the device are: IN, EN voltages: $-0.3 \mathrm{~V} $ to $26 \mathrm{~V} $, FB Voltages: $-0.3 \mathrm{~V} $ to $6 \mathrm{~V} $, SW Voltage: $-0.3 \mathrm{~V} $ to $30 \mathrm{~V} $, Peak SW Sink and Source Current: 4A[10].
The output voltage can be set using a resistor divider, $\mathrm{R} 1$ and $\mathrm{R} 2$ to the FB pin. The output voltage is given by $V_{\text {OUT } } =V_{R E F} \times\left(1+\frac{R_{1} } {R_{2} } \right)$ where the internal reference VREF is 0.6V (Typical)[11].
