MPQ2451-5/33-AEC1
36V, 2.2MHz, 0.6A, Step-Down Converter
AEC-Q100 Qualified
DESCRIPTION
The MPQ2451-5/33 is a high-frequency, step-
down, switching regulator with an integrated,
high-voltage, high-side power MOSFET. It
efficiently outputs up to 0.6A, with current-mode
control for fast loop response.
The wide 3.3V-to-36V input range accommodates
a variety of automotive step-down applications,
and the 3μA shutdown-mode quiescent current
allows use in battery-powered applications.
The MPQ2451-5/33 achieves high power-
conversion efficiency over a wide load range by
scaling down the switching frequency under
light-load conditions to reduce switching and
gate driving losses.
Frequency fold-back prevents inductor current
runaway during start-up. Thermal shutdown
provides reliable, fault-tolerant operation.
The MPQ2451-5/33 is available in cost-effective
SOT23-6L and QFN-6L packages.
