MP2454

36V, 0.6A

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

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.



60μA Operating Quiescent Current

Wide 3.3V to 36V Operating Input Range

200mΩ Internal Power MOSFET

Up to 2.3MHz Programmable Switching

Frequency

Stable with Ceramic Output Capacitors

Internal Compensation



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

cold-crank conditions.

External Soft Start

> 90% Efficiency

Low Dropout Operation for Cold Crank

3.5μA Low Shutdown Supply Current

Synchronization to External Clock

Power Good Output

Programmable Power Good Delay Time

MSOP-10 EP and QFN-10 (3mm x 3mm)

Packages

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

driving losses.

APPLICATIONS



High-Voltage Power Conversion

Automotive Systems

Industrial Power Systems

Distributed Power Systems

Battery Powered Systems

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

voltage.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For

MPS green status, please visit the MPS website under Quality Assurance.

The MP2454 is available in MSOP-10 EP and

QFN-10 (3mm x 3mm) packages.
