DESCRIPTION
4 T' e0 Z5 n4 A& KThe ZCC2467 is a high frequency step-down switching regulator with integrated
: c" t7 z) C) X8 Tinternal 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.
# T% R. c4 n8 a) {- Q3 LHigh power conversion efficiency over a wide load range is achieved by
scaling down the switching frequency at light load condition to reduce the
4 \2 F6 {# J8 E: mswitching and gate driving losses.
The frequency foldback prevents inductor current runaway during startup and
thermal shutdown provides reliable, fault tolerant operation.
