DESCRIPTION

▲ The ZCC2467 is a high frequency step-down switching regulator with integrated
▲ internal high-side, high voltage power MOSFET. It provides 3.0A output with
▲ current mode control for fast loop response and easy compensation.
▲ The wide 6V to 40V input range accommodates a variety of step-down
▲ applications, including those in automotive systems. A 100μA operational
▲ quiescent current allows use in battery-powered applications.
▲ High power conversion efficiency over a wide load range is achieved by
▲ scaling down the switching frequency at light load condition to reduce the
▲ switching and gate driving losses.
▲ The frequency foldback prevents inductor current runaway during startup and
▲ thermal shutdown provides reliable, fault tolerant operation.
▲ The ZCC2467 is available in thermally enhanced SOIC8 package.
