The SY83088J is a high efficiency synchronous buck converter operating over a wide input voltage range of 4V to 24V and capable of delivering up to 8A current. It integrates low R_DS(ON) top and bottom MOSFETs to minimize the conduction loss. It operates at a pseudo-constant frequency of 600kHz, to enable the use of small size inductor and capacitors. The SY83088J also provides a fixed 3.3V LDO with 100mA current capability, which can be used to power the external peripheries. The 3.3V LDO can switch to BYP input to reduce power loss.
