SY21288B Datasheet | Silergy

High Efficiency Fast Response, 8A, 28V Input Synchronous Buck Converter with 100mA 3.3V LDO General Description Features The SY21288B 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 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 SY21288B also provides a fixed 3.3V LDO with 100mA current capability, which can be used to power the external peripheries, such as the keyboard controller in notebook. The 3.3V LDO can switch to buck...
