| 3A, 28V, 500kHz Synchronous Step-Down Converter DESCRIPTION The EUP3476 is a 500KHz fixed frequency synchronous current mode buck regulator. The device integrates both 135m[ high-side switch and 90m[ 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 EUP3476 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. In shutdown mode, the supply current drops below 1A. The EUP3476 is available in SOP-8 package with the exposed pad. EUP3476 FEATURES 3A Continuous Output Current 110ns Minimum On Time Integrated 135m[ High Side Switch Integrated 90m[ Low Side Switch Wide 4.5V to 28V Operating Input Range Output Adjustable from 0.8V to 24V Up to 95% Efficiency Programmable Soft-Start <1A Shutdown Current Available in 500KHz Fixed Switching Frequency Thermal Shutdown and Over Current Protection Input Under Voltage Lockout Available in SOP-8 (EP) Package RoHS Compliant and 100% Lead(Pb)-Free Halogen-Free APPLICATIONS Distributed Power Systems Networking Systems FPGA, DSP, ASIC Power Supplies Typical Application Circuit Figure 1.
