Converter integrates inductor, targets RF apps

The EP5368QI synchronous buck converter with an integrated inductor, delivers low output ripple in a 3 x 3 x 1.1-mm QFN package. The solution requires only two multilayer ceramic capacitors with a footprint of 22 sq mm. The device is well suited for RF, analog, and high-speed digital applications where switcher noise can limit data throughput and cause failure in spectral compliance.

The part features a proprietary low-loss integrated inductor, PWM controller, MOSFETs, and a compensation network. It has a 4-MHz switching frequency, and achieves up to 94% efficiency. It provides 600 mA of continuous output current over the industrial temperature range and 700 mA over the commercial temperature range. The device uses a 3-pin voltage selector to choose one of seven preset common output voltages or an external resistor divider. ($0.98 ea/10,000 available now.)
