Synchronous buck converters work with ceramic or electrolytic output capacitors

21-02-2017 | Digikey | Power

Richtek's RT6204 is a synchronous buck converter with a wide input range of 5.5V to 60V and an output range adjustable from 0.8V to 50V with 500mA current capability. It is available now from Digi-Key. The device switches at 350kHz and is housed in a SOP-8 thermally effective package. The wide input range in combination with high step-down capability makes it suitable for virtually any industrial application range, from battery fed automotive to 12V, 24V and 48V industrial supplies. Featuring PSM mode for enhanced light load efficiency, the device uses current mode topology with external compensation, allowing great flexibility in loop tuning using either ceramic or electrolytic output capacitors. The 80V max rating makes this IC very tolerant to hot-swapping and other supply voltage transients. Slew rate limited switching helps to reduce EMI radiation.
