Low-voltage AC-DC modules that also accept polarity-free DC input — for appliances, smart home and control modules.

When input and output must not share a ground — isolated buck and buck-boost modules for industrial control and instrumentation.

How buck-boost converters keep the output regulated whether input voltage is above or below the target rail.

Step-up modules with external-MOS synchronous design, bypass pass-through and wide input tolerance.

Die-cast aluminum Y1–Y4 housings with strong heat sinking and protection — built for harsh environments.

Higher-current step-down modules in aluminum housings for demanding vehicle and industrial loads.

Aluminum-profile housed buck converters balancing heat dissipation, size and cost for industrial use.

Compact J1–J3 plastic modules for low-power buck applications with wide input range and stable output.

When a MOSFET replaces the freewheeling diode, efficiency rises — here is how synchronous rectification works and when it pays off.

Switching element, freewheeling diode, inductor and capacitor — and how PWM duty cycle controls the output voltage of every buck converter.
