降压 (Buck) 变换器 Vin max 7V~30V

The SY8104 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of delivering 4.0A current. The SY8104 operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.\r\n\r\n L ·low RDS(ON) for internal switches (top/bottom):50m /30m\r\n·4.5-18V input voltage range\r\n·4.0A output current capability\r\n·500 kHz switching frequency\r\n·Instant PWM architecture to achieve fast transient responses.\r\n·Internal softstart limits the inrush current\r\n·1.5% 0.6V reference\r;
