SY21612C - Single-Inductor Synchronous Step-Up/Down Regulator

General Description

The SY21612C high-voltage synchronous buckboost converter operates over a wide input voltage range from 4V to 28V with 10A maximum average inductor current capability.

The four integrated lowRDS(ON) switches minimize conduction loss.

Key Features

  • 4V to 28V Operating Input Voltage Range.
  • 38V Absolute Maximum Input Voltage.
  • Low RDS(ON) for Internal Switches: 25mΩ.
  • 250kHz/500kHz Selectable Switching Frequency.
  • Soft-Start Inrush Current limit.

SY21612C High-Efficiency, 38V Maximum Input Single-Inductor Synchronous Step-Up/Down Regulator General Description The SY21612C high-voltage synchronous buckboost converter operates over a wide input voltage range from 4V to 28V with 10A maximum average inductor current capability. The four integrated lowRDS(ON) switches minimize conduction loss. The SY21612C offers protection against multiple conditions, including short-circuit, overcurrent, overvoltage, and overtemperature. The SY21612C is highly integrated, so only the input and output capacitors, inductor, and feedback resistors need to be selected for the targeted application specifications. The SY21612C is available in a compact QFN4×432 package.
