SY21286B Datasheet | Silergy

High Efficiency, Fast Response, 6A, 28V Input, Fixed 3.338V Output Synchronous Buck Converter with 100mA 3.3V LDO General Description Features The SY21286B is a high efficiency synchronous buck converter operating over a wide input voltage range of 4.5V to 24V and capable of delivering up to 6A current. It integrates low RDS(ON) top and bottom MOSFETs to minimize the conduction loss. It operates at a pseudoconstant frequency of 600kHz, to enable the use of small size inductor and capacitors. The SY21286B 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 buck converter output to reduce...
