High Efficiency 1MHz, 2A Step Up Regulator
General Description
TD8228 is a high efficiency, current-mode control Boost DC to
DC regulator with an integrated 120mΩ R
DS(ON)
N-channel
MOSFET. The fixed 1MHz switching frequency and internal
compensation reduce external component count and save
the PCB space. The build-in internal soft start circuitry
minimizes the inrush current at start-up.
