Chipscale Converter Touts Low-Noise Operation

Mon, 03/31/2008 - 5:03am

EP5368QI converterWell-suited for applications where switcher noise can limit data throughput and cause failure in spectral compliance, the EP5368QI mA synchronous buck converter has an integrated inductor, PWM controller, MOSFETS, and compensation network to significantly simplify design, reduce the parts count, and provide for inherently low-noise operation. Requiring just 2 MLCC caps for a solution footprint of 22 mm², the 3 mm × 3 mm × 1.1 mm device has a 4 MHz switching frequency, achieves up to 94 percent efficiency, and provides up to 700 mA over the commercial temperature range. The converter uses a 3-pin voltage selector to choose one of seven preset common output voltages or an external resistor divider. $0.98 for quantities of 10,000.
