Power Supplies Board Mount

Board-mount power supplies convert and regulate voltage levels directly on the PCB — critical for powering every electronic subsystem reliably and efficiently. This category includes DC-DC converters (isolated, non-isolated, step-down/buck, step-up/boost, buck-boost), AC-DC converters (board-mount PSU modules), point-of-load (PoL) regulators, LDO (low dropout) voltage regulators, and LED drivers. Key parameters: input voltage range, output voltage/current, efficiency (peak and full-load), switching frequency, line/load regulation, ripple/noise, isolation voltage (for isolated converters), and protection features (OVP, OCP, SCP, thermal shutdown). Package formats: SIP, DIP, SMD module, QFN, BGA. Digital power modules with PMBus/I²C telemetry enable real-time monitoring of voltage, current, and temperature. Popular manufacturers: Texas Instruments, Analog Devices (Linear Technology), Murata, Recom, Traco Power, Mean Well, Vicor, and XP Power.
