SY8121BABC中文资料降压 (Buck) 变换器 Vin max 7V~30V数据手册Silergy规格书

描述 Description

SY8121B develops high efficiency synchronous stepdown DC-DC converter capable of delivering 2A load current. SY8121B 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.

SY8121B always operates under continuous condition mode, low output ripple and small inductor and capacitor size are achieved with 1.2MHz switching frequency.

特性 Features

• Low RDS(ON) for internal switches (top/bottom):170/160 mΩ
• 4.5-18V input voltage range
• 2A load current capability
• Instant PWM architecture to achieve fast transient responses
• Internal softstart limits the inrush current
• 2% 0.6V reference
