Plug & Play, This 5V to 12V DC converter is really handy when travelling or outdoors, just power it with a 5V 2A power bank and you can start running your 12V devices. USB Input: 5V A male; DC Output: 12.0V; Max current: 0.6A; PLEASE NOTE: The size of the DC Connector is OD: 3.5 mm and ID: 1.35 mm.
While it is normally used for buck regulation from 12v to 5v, it can also do inverting and in your specific need, boost regulation by moving the circuit around. The car chargers will have an okay sized capacitor, diode, and typically 220 µh inductor needed, though the timing capacitor would most likely need to be changed.
USB-C PD & 5V/9V/12V/20V. Now you know that the USB-C has the potential to provide much more power through the power delivery scheme. When you first plug a USB-C device into a USB-C PD power supply, the power supply will send over 5V, and this should be adequate to run the power supply circuitry and get everything started.
Step up DC-DC converter is based on LM2577-ADJ IC, this project provides 12V output using 5V input, maximum output load of 800mA. The LM2577 are monolithic integrated circuits that provide all of the power and control functions for step-up (boost), fly-back, and forward converter switching regulators. The device is available in three different
