EN5337QI

3A Voltage Mode Synchronous Buck PWM

DC-DC Converter with Integrated Inductor

Description

Features

The EN5337QI is a Power Supply on a Chip

(PwrSoC) DC-DC converter. It integrates

MOSFET switches, all small-signal circuits,

compensation, and the inductor in an advanced

4mm x 7mm QFN package.

• Integrated Inductor, MOSFETS, Controller

• Total Power Solution ≈ 75mm²

• Minimal external components.

• 3A Continuous Output Current Capability

• 5MHz operating frequency. Switching

frequency can be phase locked to an external

clock.

The EN5337QI 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

distributed power architectures. 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.

• High efficiency, up to 92%.

• Wide input voltage range of 2.375V to 5.5V.

• Output Enable pin and Power OK signal.

• Programmable soft-start time.

• Under Voltage Lockout, Over Current, Short

Circuit and Thermal Protection.

• RoHS compliant, MSL level 3, 260C reflow.

Applications

• Point of load regulation for low-power

processors, network processors, DSPs,

FPGAs, and ASICs

The Enpirion solution 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.

• Noise sensitive applications such as A/V, RF

and Gbit I/O

• Low voltage, distributed power architectures

All Enpirion products are RoHS compliant and

lead-free manufacturing environment compatible.

with 2.5V, 3.3V or 5V rails

• Computing, Networking, DSL, STB, DVR,

DTV, iPC

• Ripple sensitive applications

• Beat frequency sensitive applications
