Frequently Asked Questions

How do I choose between AC-DC and DC-DC converters?

The choice depends on your input power source: (1) AC-DC converters - used when input is AC mains (85-265VAC). Include rectification, PFC (if required), and isolation. Higher complexity and cost but necessary for line-powered equipment. (2) DC-DC converters - used when input is already DC (battery, adapter output, bus voltage). More compact and efficient, no isolation (unless using isolated topology). (3) Application examples - AC-DC for wall-powered devices (TVs, computers, appliances)

DC-DC for battery-powered devices, internal voltage regulation. (4) Safety - AC-DC requires isolation and safety certifications

DC-DC may be non-isolated for internal use. (5) Efficiency - DC-DC typically 90-95%

AC-DC typically 85-92% due to additional stages.

Use AC-DC for line-powered equipment; DC-DC for battery or DC bus applications.

What is the difference between switching and linear regulators?

Switching regulators (buck, boost) vs linear regulators (LDO): (1) Efficiency - switching regulators are 85-95% efficient

linear regulators efficiency = Vout/Vin (e.g., 3.3V from 5V = 66%). (2) Heat - linear regulators dissipate (Vin-Vout) × I as heat

switching regulators run cooler. (3) Noise - linear regulators have very low output noise

switching regulators have ripple and EMI. (4) Complexity - linear regulators need only input/output capacitors

switching regulators need inductor and more components. (5) Cost - linear regulators are cheaper and smaller. (6) Use cases - linear for low dropout, low noise, simple apps

switching for high efficiency, large voltage differences. Many systems use switching for main conversion and LDO for post-regulation.

Use switching for high efficiency and large voltage drops; LDO for low noise and simplicity.
