    The SY20621B is a high efficiency 2.4MHz synchronous step down DC/DC module converter capable of delivering up to 2A output current. It can operate over a wide input voltage range from 2.5V to 5.5V. It integrates main switch, synchronous switch and inductor inside to minimize the conduction loss.The SQ76002B is in a space saving, low profile MDFN1.9×1.75-6 package. Only input capacitors, output capacitor and FB resistor divider are needed to complete the design.
