概述

SY21275 is a high efficiency, current-mode control Boost regulator. The device integrates a low RDS(ON) N-channel MOSFET for high efficiency. The fixed 500kHz switching frequency achieves high efficiency and fast transient response. The external programmable soft start time minimizes the inrush current at start-up.


SY21275 is available in compact DFN3×3-10 package.

Applications

  • TFT LCD Panels AVDD
