Synchronous Buck Converter with Both 16 µA Quiescent Current and 20 mV Transient Response
Fairchild Semiconductor introduces the FAN5350 , a 3 MHz/600 mA DC/DC synchronous buck converter featuring 16µA quiescent current, 20 mV transient response and low-voltage ripple. Designed to power DSP core processors, application processors and I/O interfaces, the device utilizes the company’s proprietary ultra-fast architecture that is specifically designed to simultaneously provide industry-leading quiescent current and transient-response performance. Its 3 MHz switching allows the device to employ small chip inductors (1µH) and still maintain low ripple. Package options include both 1.00 mm x 1.37 mm WLCSP and 3 mm x 3 mm MLP packages. This high-performance, compact converter enables designers to meet next-generation load requirements while preserving battery life and saving board space in cell phones, media players, GPS devices, Bluetooth headsets and other single-cell 2.7V to 5.5V lithium-ion-powered portable applications.
