大电流3A40V同步降压芯片

The SY8303 develops a high efficiency synchronous step-down DC-DC converter capable of delivering 3A load current. The SY8303 operates over a wide input voltage range from 4.5V to 40V and integrates main switch and synchronous switch with very low RDsxo) to minimize the conduction loss.\r\n\r\n T • Low RDS(ON) for internal switches (top/bottom):110/70 mΩ\r\n• 4.5-40V input voltage range\r\n• Internal compensation\r\n• Internal 1ms soft-start limits the inrush current\r\n• Adjustable switching frequency range: 500kHz to2.5MHz\r\n• 3A output current capability\r\n• 1.5% 0.6V reference\r\n•;

3 V, Dual, Serial Input Complete 12-Bit DAC

GENERAL DESCRIPTION The AD8303 is a complete (includes internal reference) dual,12-bit, voltage output digital-to-analog converter designed to operate from a single +3 volt supply. Built using a CBCMOSprocess, this monolithic DAC offers the user low cost and ease of-use in single-supply +3 volt s
