EUP3485 - 500KHz Synchronous Step-Down Converter

Datasheet Summary

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.

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.

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.
