The Future of Analog IC Technology
MP2420
75V, 0.3A Synchronous
Step-Down Converter with Watchdog
DESCRIPTION
The MP2420 is a step-down switching regulator
with integrated high- and low-side, high-voltage
power MOSFETs. It achieves a highly efficient
output of up to 0.3A, and the integrated
watchdog adds additional security redundancy
to the system.
The wide 4.5V to 75V input range accommodates
a variety of step-down applications in an
automotive environment. A 5μA shutdown
mode quiescent current in a full temperature
range is ideal for battery-powered applications.
The MP2420 allows for high-power conversion
efficiency over a wide load range by scaling
down the switching frequency under light-load
conditions to reduce switching and gate driver
losses. The start-up switching frequency and
short circuit can also be scaled down to prevent
an inductor current runaway.
Full protection features include under-voltage
lockout (UVLO) and thermal shutdown. Thermal
shutdown provides reliable, fault-tolerant
operation.
The MP2420 is available in a TSSOP-16 EP
package.
