EN5310

1A Voltage Mode Synchronous Buck PWM

DC-DC Converter

ENPIRION

Description

Features

The EN5310 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.

• 1000mA output current capacity

• External inductor is NOT required

• Lead-Free packaging

• 5MHz operating frequency

• More than 90% efficient

• V_OUTaccuracy of 2% over line, load and

temperature

• 1/2 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

programming output voltages from 0.9V to 4.0V

• Output enable pin and Power OK signal

• Programmable soft-start time

• Programmable over-current protection

• Thermal shutdown, short circuit, over-voltage and

under-voltage protection

The EN5310 significantly helps in system design and

productivity by offering greatly simplified board

design, layout and manufacturing requirements. In

addition, a reduction in the number of vendors

required for the complete power solution helps to

enable an overall system cost savings.

Applications

• VOIP phones, video telephones

Typical Application Circuit

• 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
