RT6204 Synchronous Buck Converter

Richtek's RT6204 is a synchronous buck converter with a wide input range of 5.5 V to 60 V and an output range adjustable from 0.8 V to 50 V with 500 mA current capability. The RT6204 switches at 350 kHz 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 12 V / 24 V / 48 V industrial supplies.

Featuring PSM mode for enhanced light load efficiency, the RT6204 uses current mode topology with external compensation, allowing great flexibility in loop tuning using either ceramic or electrolytic output capacitors. The 80 V max rating makes this IC very tolerant to hot-swapping and other supply voltage transients. Slew rate limited switching helps to reduce EMI radiation.
