CYP9451 Step-Down Converter Dc-DC chip
DESCRIPTION:
The CYP9451 is a high frequency (1.8MHz) step-down switching regulator with integrated internal high-side high voltage power MOSFET. It provides single 0.6A (or less) highly efficient output with current mode control for fast loop response.
The wide input range (4.2V to 40V) accommodates a variety of step-down applications under mobile environment input conditions. Low shutdown mode quiescent current of 1μA is suitable for battery-powered applications.
High efficiency at light load condition is achieved by scaling down the switching frequency to reduce the switching and gate driving losses. The frequency folding technique helps prevent the inductance current from running out of control at startup. Hot shutdown provides reliable, fault tolerant operation.
