Enpirion is a premier analog semiconductor company with expertise in highly integrated power management solutions. Enpirion has developed the industry’s first family of Power Systems-on-a-Chip (PowerSoC) DC-DC converters featuring integrated inductors, which uniquely enables the combination of high efficiency, industry leading footprint and low noise performance.

Features

• Integrated Inductor
• 500 mA continuous output current
• 2.4 V to 5.5 V input range
• Up to 95% peak efficiency
• Excellent transient response, low ripple
• Requires two MLCC filter capacitors
• 3-pin VID output voltage programming
• 4 mm x 5 mm x 1.1 mm package
• Fully RoHS compliant and Pb-free manufacturing line compatible

The Enpirion EP5352QI represents a revolution in low-power switching converters. The total solution footprint is 36mm2, without compromising efficiency. Requiring two external components, the EP5352QI makes regulator design a breeze.

A complete power system-on-a-chip (PowerSoC), the EP5352QI integrates power switches, Inductor, gate drive, controller, and loop compensation in a tiny 5 mm x 4 mm package. The 1.1mm profile and small footprint enables the use of this part where space is at a premium.

The EP5352QI utilizes a 3-pin VID output voltage selector that allows the designer to choose one of seven pre-defined output voltage levels; or an external voltage divider can be employed to set the output voltage.

This product is an excellent choice for low-power mobile applications such as smart-phone, personal media player or PDAs.
