Silergy SY21286A
The SY21286A 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.| Part No. | SY21286A |

GENERAL DESCRIPTION
The SY21286A also provides a bypass switch which allows the VCC to be powered by external 3.3V power supply, further reduce the power consumption of the entire system. Silergy’s constant on-time and ripple-based control strategy supports high input/output voltage ratios (low duty cycles), and fast transient response while maintaining a near constant operating frequency over line, load and output voltage ranges. This control method provides stable operation without complex compensation, including when using low ESR output ceramic capacitors. The SY21286A provides cycle-by-cycle current limit, input under voltage lockout, internal soft-start, output under voltage protection, over voltage protection and over temperature protection, to guarantee safe operation in all operating conditions.FEATURES
