3 mm enamelled copper wire on a small toroidal core, lifted from an old CFL circuit board.

In my prototype, I have used a вЂњhome-madeвЂќ 100uH inductor as L1. Last but not least, say that the diode (D1) has to be a fast, not worth as the 1N400X rectifiers, the 1N5817 is recommended schottky type, characterized by high response time and low internal resistance, which is what ideal for this type of boost-converter circuits. As you can see, at 7.5v it provides 0.84A and not 0.33A. If you do not have a LCR meter the inductive part (L1) of the circuit is a bit more complicated to make! Capacitors (C1 & C2) also recommended by the manufacturer for this circuit is a bit hard to get, I have used tantalum types recovered from a discarded smps circuit board. So, if the USB port can deliver 2.5W at 5V that means at best the maximum current at 7.5V would be 2.5W / 7.5V 0.33A or 330mA (since 7.5V x 0.33A is 2.5W).

HT7750A consists of an oscillator, a PFM control circuit, a driver transistor, a reference voltage unit, and a high speed comparator. Waremew 8 Connectors Adapter USB to DC Power Cable & USB 5V to DC 12V Converter Step Up Voltage Converter Power Cable,Blue Tooth Headset. CMOS technology ensures ultra low supply current and makes them ideal for battery-operated applications powered from one or more cells. It comes with a six-foot cable, 60W output, and is compatible with any Type C device. They require only three external components to provide a fixed output voltage of 5.0V. The chip features extremely low start-up voltage and high output voltage accuracy. Schematic of 3V to 5V Booster CircuitДЄt the heart of the circuit is one tiny chip HT7750A, which is a вЂњpulse frequency modulationвЂќ (PFM) step-up DC/DC converter with high efficiency and low ripple. This circuit can be used to power your 5V microcontroller/similar circuits from two standard AA cells (1.5V x2). Presented here is the simple circuit of one boost (step-up) converter, which can output steady 5VDC supply from a 3VDC input. However, in applications that involve providing a DC voltage to only the microcontroller and a few other low-current devices, transformer-based power supplies may not be cost effective. Traditionally, this has been done with a transformer and rectifier.

Note: The Module has Output short circuit protection, but please do not a short circuit for a long time to avoid damage due to overheating.There are several ways to convert an AC voltage at a wall receptacle into the DC voltage required by a microcontroller. output with 12V Input) it does not need to enhance heat dissipation.

please enhance heat dissipation when fully used for load output(i.e.
