MP2452  
1A, 36V, 1MHz  
Step-Down Converter  
The Future of Analog IC Technology  
FEATURES  
DESCRIPTION  
1A Continuous Load Current  
The MP2452 is a high frequency (1MHz) step-  
down switching regulator with integrated  
internal high-side high voltage power MOSFET.  
It provides up to 1A highly efficient output  
current with current mode control for fast loop  
response.  
130 µA Operating Quiescent Current  
Wide 3.3V to 36V Operating Input Range  
500 mInternal Power MOSFET  
1MHz fixed Switching Frequency  
Internally compensated  
Stable with Ceramic Output Capacitors  
Internal Soft-Start  
> 90% Efficiency  
+0.794V FB Reference Voltage  
Output Adjustable from +0.794V to 33V  
3µA Low Shutdown Supply Current  
2mm x 3mm QFN8 Package  
The wide 3.3V to 36V input range accommodates  
a variety of step-down applications in automotive  
input environment. A 3µA shutdown mode  
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.  
APPLICATIONS  
High Voltage Power Conversion  
Automotive Systems  
Industrial Power Systems  
Distributed Power Systems  
Battery Powered Systems  
Frequency fold-back helps prevent inductor current  
runaway during start-up. Thermal shutdown  
provides reliable, fault-tolerant operation.  
The MP2452 is available in the 2mm x 3mm QFN8  
package.
