3A Low Profile Synchronous Buck DC-DC Converter
Description
EN5339QI 3A Low Profile Synchronous Buck DC-DC Converter with Integrated Inductor
RoHS Compliant Halogen Free
Description
The EN5339 is a low profile 3A, high efficiency, synchronous buck PowerSoC.
The device features integrated inductor, PWM controller, MOSFETS, and compensation providing the smallest possible solution size.
The EN5339QI is pin compatible with Enpirion’s EN5322QI 2A PowerSoC enabling a family of scalable solutions.
The high frequency operation allows for the use of tiny MLCC capacitors.
It also enables a very wide control loop bandwidth providing excellent transient performance and reduced output impedance.
The internal compensation is designed for unconditional stability across all operating conditions.
The output voltage is set via a simple and flexible resistor divider network.
The very high efficiency and low profile design make this device optimal for space constrained applications requiring up to 3A of continuous output current.
