The principle of the transformer is to use the principle of electromagnetic induction to convert the input voltage into a higher voltage.
The so-called booster chip refers to the integrated circuit used for direct current booster, which contains a complete set of circuits such as vibration, sampling, and energy storage. It's not the same as a triode! One or two triodes can make a simple booster circuit, but the efficiency is far less than that of a dedicated chip.
This PW5100 boost IC is ideal for you, it can adjust the voltage range of 3-5VUp to 5V, the maximum efficiency is up to 95%, the operating frequency is 2MHz, and the static current is only 10uA. Its low power consumption makes it particularly useful in applications where high performance is required.

Zhenbang Micro Technology launched a new 5V litre 12V (B628 silkscreen)C converter circuit, closing the switch will cause an increase in current through the inductor.
2, error amplifier: The role of error amplifier is to amplify the difference between the feedback voltage (FB pin voltage) and the reference voltage, and then use the signal to control the duty ratio of the PWM output signal. Temperature protection: When the temperature is higher than the limit value, the chip stops working.
