SY20418
Description
The SY20418 is a high efficiency, synchronous boost converter with an input voltage range of 0.7V to 5V which can provide an output voltage range between 1.8V and 5.25V.
The device uses a current mode hysteretic control architecture to enable good transient performance and stable operation. The low start-up voltage and low operating current, makes this converter ideal for battery operated applications using single-cell or dual-cell alkaline, Ni MH or Ni Cad batteries. The low Iq during shutdown mode enables long battery life. Low Rdson MSOFETs are used for the main and synchronous switches to obtain a good efficiency.
The SY20418 is available in a pact SOT-363 package.
