The Future of Analog IC Technology
MP2498
Integrated 100V Load Dump Protection,
2A Step-Down Regulator
DESCRIPTION
The MP2498 is a high frequency monolithic
step-down switch mode converter with
integrated buck internal high side high voltage
power MOSFET and an integrated input
overvoltage protection. It provides 2A output
with current mode control for fast loop response
and easy compensation.
The wide 6.5V to 30V input range of the buck
regulator accommodates a variety of step-down
applications, including those in automotive input
environment.
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.
Fault condition protection includes cycle-by-
cycle current limiting and thermal shutdown.
The MP2498 can survive high-voltage
transients such as those found in automotive
and industrial applications.
The MP2498 requires a minimum number of
readily available standard external components.
The MP2498 is available in a 28-pin QFN
package.
