Description The EN5330 is a Power System on a Chip DC-DC converter. It is specifically designed to meet the precise voltage and fast transient requirements of present and future high-performance, low-power processor, DSP, FPGA, memory boards and system level applications in a distributed power architecture. Advanced circuit techniques, ultra high switching frequency, and very advanced, high-density, integrated circuit and proprietary inductor technology deliver high-quality, ultra compact, non-isolated DC DC conversion. Operating this converter requires only three external components that include small value input and output ceramic capacitors and a soft-start capacitor. Features • Up to 10W output power (at VOUT=3.3V) • External inductor is NOT required • Lead-Free packaging • 5MHz operating frequency • More than 90% efficient • VOUT accuracy of 2% over line, load and temperature • 1/3 the board area of discrete component solutions • Very fast transient response • All high speed switching signals contained inside the part • Wide input voltage range of 2.375V to 5.5V • Digital voltage selector with options for common output voltages from 0.8V to 3.3V • External resistor divider and OVP option for output voltages from 0.8V to VIN-600mV • Output enable pin and Power OK signal • Programmable soft-start time • Over-current protection • Thermal shutdown, short circuit, output over voltage and input under-voltage protection Applications • Servers, workstations and PCs • Broadband, networking, LAN/WAN, optical telecommunications equipment • Point of load regulation for low-power processors, network processors, DSPs, FPGAs, and ASICs • Low voltage, distributed power architectures with 2.5V, 3.3V or 5V rails
