EUP3475
3A, 28V, 1MHz Synchronous Step-Down Converter
DESCRIPTION
The EUP3475 is a 1MHz 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. Current mode control provides fast transient response and cycle-by-cycle current limit.
The EUP3475 features short circuit and thermal protection circuits to increase system reliability. Externally programmable soft-start allows for proper power on sequencing with respect to other power supllies and avoids input inrush current during startup.
