DC-DC Internally, the DC power supply is first converted to AC power supply AC. Usually a self-oscillating circuit, so outside the need for discrete components such as inductors. The output then passes through the integral filter and returns to the DC power supply. Since the AC power supply is generated, it is easy to perform step-up and step-down. Example
LDO LDO is a low dropout regulator (LDO), which is a low dropout linear regulator compared to a conventional linear regulator. Only can reduce voltage. The nature of LDOs is the conversion of heat in exchange for voltage, so the drive capability and thermal power are closely related. Example

DC - DC

DC-DC includes boost, buck, Boost/buck, and inverting structure. It features high efficiency, high output current, low quiescent current, and wide input voltage range. With the increase of integration, the peripheral circuits of many new DC-DC converters only require inductors and filter capacitors; however, the output ripple and switching noise of such power controllers are relatively large and the cost is relatively high.
