Results forSY20019ARC

The SY20019 high-efficiency 1.5MHz synchronous step-down DC/DC regulator operates over a wide input voltage range of 2.5V to 5.5V, and can deliver an output current up to 1A. It integrates a main switch and a synchronous switch with very low RDS(ON) to minimize conduction loss. The 1.5MHz pseudoconstant switching frequency allows for small external inductor and capacitor values. The SY20019 uses constant-off-time and peak-current-mode control to achieve fast transient responses. It provides overcurrent and short-circuit protection. The SY20019 is available in a space-saving, low-profile SOT563 package.
