The Future of Analog IC Technology
The MP2454 is a frequency-programmable
(350kHz to 2.3MHz), step-down switching
regulator with an integrated internal high-side,
high-voltage power MOSFET. It outputs
efficiently up to 0.6A and has current-mode
control for fast loop response.
The wide 3.3V to 36V input range accommodates a
variety of step-down applications in automotive-
input environments. A 3.5μA shutdown mode
quiescent current allows for use in battery-
powered applications. Also, the device has a high
duty cycle and low drop-out mode for automotive
The MP2454 achieves high-power conversion
efficiency over a wide load range by scaling
down the switching frequency at light-load
conditions to reduce both switching and gate
Frequency foldback prevents inductor current
runaway during start-up and short circuit.
Thermal shutdown provides reliable, fault-tolerant
operation. An open-drain power good (PG) signal
indicates when the output is within its nominal
The MP2454 is available in MSOP-10 EP and
QFN-10 (3mm x 3mm) packages.
