SYR838PKC

SYR837/SYR838 is a high efficiency 2.4MHz synchronous step down DC/DC regulator IC capable of delivering up to 6A output currents. It can operate over a wide input voltage range from 2.6V to 5.5V and integrate main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss. The output voltage can be programmed from 0.7125V to 1.5V through I2 C interface.

SYR837/SYR838 is in a space saving, low profile CSP1.56*1.96-20 package.

Features
• Input voltage range: 2.6V to 5.5V
• 2.4 MHz switching frequency minimizes the external components
• Typical 65uA quiescent current
• Low RDS(ON) for internal switches (PFET/NFET):28mΩ/17mΩ
• Programmable Output Voltage: 0.7125V to 1.5V in 12.5mV steps
• 6A continuous output current capability.
• Capable for 0.25uH inductor and 22uF Ceramic Capacitor
