비효율적인 선형 레귤레이터를 대체할 완벽한 대안은 스위칭 레귤레이터입니다. 이러한 제품은 효율성 97%를 보장하는 컨버터로 비효율적인 선형 레귤레이터를 대신할 수 있기 때문에 히트싱크가 없어도 됩니다. 드롭인 핀 호환 방식으로 대체하므로, PCB 레이아웃을 변경하지 않고도 기존 디자인에 손쉽게 통합됩니다. RECOM은 완전 자동화된 제조 공정을 활용한 결과, 생산 비용은 절감하면서도 품질이나 안정성을 떨어뜨리지 않을 수 있었습니다. 대표적인 결실이 바로 새로 나온 K 시리즈입니다.

자주 묻는 질문
Linear regulators act as resistive elements, dissipating excess voltage as waste heat (often operating at efficiencies as low as 30% to 50%). Switching regulators convert voltage at up to 97% efficiency, drastically lowering thermal stress, eliminating the need for bulky heatsinks, and offering a cost-effective long-term solution for energy-conscious designs.
Yes. Standard 78-series switching regulators feature the exact pinout and footprint of traditional TO-220 three-terminal 78xx linear regulators (VIN, GND, VOUT). This allows a direct, cost-effective drop-in upgrade on existing PCB layouts without requiring circuit redesigns.
Through-hole (THT) options fit standard 3-pin headers for drop-in retrofits. Surface-mount (SMD/LGA) modules offer low-profile, pinless construction engineered for automated SMT pick-and-place lines, providing a cost-effective solution where vertical component clearance is strictly limited.
