Overview

Enpirion® Power Datasheet ER3105DI 500mA Wide VIN Synchronous Buck Regulator DS-1041 Datasheet The Altera® Enpirion® ER3105DI is a 500mA Synchronous buck regulator with an input range of 3V to 36V.
It provides an easy to use, high efficiency low BOM count solution for a variety of applications.
The ER3105DI integrates both high-side and low-side NMOS FET's and features a PFM mode for improved efficiency at light loads.
This feature can be disabled if forced PWM mode is desired.
The part switches at a default frequency of 500kHz but may also be programmed using an external resistor from 300kHz to 2MHz.
The ER3105DI has the ability to utilize internal or external compensation.
By integrating both NMOS devices and providing internal configuration options, minimal external components are required, reducing BOM count and complexity of design.
With the wide VIN range and reduced BOM the part provides an easy to implement design solution for a variety of applications while giving superior performance.
It provides a very robust design for industrial, battery, and FPGA power applications.
The part is available in a small Pb free 4mmx3mm DFN plastic package with an operation temperature range of -40°C to +125°C Features • Wide input voltage range 3V to 36V • Synchronous Operation for high efficiency • No compensation required • Integrated High-side and Low-side NMOS devices • Selectable PFM or forced PWM mode at light loads • Internal fixed (500kHz) or adjustable Switching frequency 300kHz to 2MHz • Continuous output current up to 500mA • Internal or external Soft-start • Minimal external components required • Power-good and enable functions available.
