DC-DC chip is a switch type power management chip, with the core function of: Efficient conversion between DC voltages (step-down, step-up, step-up/step-down), widely used for powering various electronic devices

Function:
1. High efficiency and low heat generation
2. Support high current output
3. Adjustable pressure and high flexibility
4. Suitable for battery powered, long-lasting devices
5.  ❌  Ripple and noise are greater than LDO
6.  ❌  The peripheral circuit is more complex (requiring inductance and capacitance)

Typical Applications:
1. Consumer electronics
    Mobile phones, tablets, laptops, TWS earphones, smartwatches
    → Provide power to CPU, screen, camera, and fast charging
2. Industrial equipment
    PLC、 Sensors, industrial control motherboards, motor drivers
    → Wide voltage input, stable high-power power supply
3. Automotive Electronics
    Car machine ADAS、 Car lights, cameras
    → Vehicle grade DC-DC anti-interference, wide temperature range
4. Communication and base stations
    High current, high efficiency, and high reliability power supply
5. Battery products
    Power banks, electric tools, energy storage devices
