Eutech Microelectronics EUP3476

The EUP3476 is a 500KHz fixed frequency synchronous current mode buck regulator. The device integrates both 135mΩ high-side switch and 90mΩ low-side switch that provide 3A of continuous load current over a wide operating input voltage of 4.5V to 28V.The internal synchronous power switch increases efficiency and eliminates the need for an external Schottky diode. The EUP3476 features short circuit and thermal protection circuits to increase system reliability.

DESCRIPTION

Current mode control provides fast transient response and cycle-by-cycle current limit. Externally programmable soft-start allows for proper power on sequencing with respect to other power supllies and avoids input inrush current during startup. In shutdown mode, the supply current drops below 1µA. The EUP3476 is available in SOP-8 package with the exposed pad.
