EP5358HUI

DataSheeT – enpirion® power solutions EP5358xUI 600mA PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES The EP5358xUI (x = L or H) is rated for up to 600mA of continuous output current. The EP5358xUI integrates MOSFET switches, control, compensation, and the magnetics in an advanced 2.5mm x 2.25mm micro-QFN Package. • Integrated Inductor Technology • -40°C to +85°C Ambient Temperature Range • 2.5mm x 2.25mm x 1.1mm uQFN Package • Total Solution Footprint 14mm2 Integrated magnetics enables a tiny solution footprint, low output ripple, low part-count, and high reliability, while maintaining high efficiency. The complete solution can be implemented in as little as 14mm2. • Low VOUT Ripple for RF Compatibility • High Efficiency, Up to 93% • Up to 600mA Continuous Output Current • 5 MHz Switching Frequency • 3 pin VID for Glitch Free Voltage Scaling • VOUT Range 0.6V to VIN – 0.25V • Short Circuit and Over Current Protection • UVLO and Thermal Protection • IC Level Reliability in a PowerSOC Solution The EP5358xUI uses a 3-pin VID to easily select the output voltage setting. Output voltage settings are available in 2 optimized ranges providing coverage for typical VOUT settings. The VID pins can be changed on the fly for fast dynamic voltage scaling. EP5358LUI further has the option to use an external voltage divider. The EP5358xUI is a perfect solution for noise sensitive and space constrained applications that require high efficiency.

NC (SW) pins are not to be electrically connected to any external signal, ground, or voltage. However, they must be soldered to the PCB. Failure to follow this guideline may result in part malfunction or damage to the device. Ground Power ground. Connect these pins together and to the ground electrode of the Input and output filter capacitors. Analog EP5358LUI: Feedback pin for external divider option. EP5358HUI: No Connect Ground Sense pin for preset output voltages. Refer to application section for proper configuration. Analog Analog ground. This is the quiet ground for the internal control circuitry, and the ground return for external feedback voltage divider. Power Regulated Output Voltage. Refer to application section for proper layout and decoupling. Analog Output voltage select. VS2 = pin 9, VS1 = pin 10, VS0 = pin 11.
