Anritsu MP1570
Telecom / Utility
Description
This unit has a monolithic synchronous buck regulator.
The device integrates 100mΩ MOSFETS that provide 3A continuous load
current over a wide operating input voltage of 4.75V to 23V.
Current mode control provides fast transient response and cycle by cycle current limit.
An adjustable soft start prevents inrush current at turn on.
In shutdown mode, the output is actively discharged by transferring energy in the
output capacitor to the input capacitor, dropping the supply current to 1µA.
