EUP3485
4A, 18V, 500KHz Synchronous
Step-Down Converter
DESCRIPTION
The EUP3485 is a 500KHz fixed frequency
synchronous current mode buck regulator. The device
integrates both 110mΩ high-side switch and 30mΩ
low-side switch that provide 4A of continuous load
current over a wide operating input voltage of 4.5V to
18V. The internal synchronous power switch increases
efficiency and eliminates the need for an external
Schottky diode. Current mode control provides fast
transient response and cycle-by-cycle current limit.
The EUP3485 features short circuit and thermal
protection circuits to increase system reliability. In
shutdown mode, the supply current drops below 1µA.
The EUP3485 is available in SOP-8 package with an
exposed pad.
