ER3105DI Description

Short technical summary and product information.

The Altera Enpirion ER3105DI is a 500mA synchronous buck regulator featuring a wide input voltage range from 3V to 36V. This device provides an easy-to-use, high-efficiency solution with a low Bill of Materials (BOM) count for various applications.

 

The ER3105DI integrates high-side and low-side NMOS FETs and includes a selectable PFM or forced PWM mode for efficiency at light loads. The switching frequency can be programmed from 300kHz to 2MHz using an external resistor, with a default frequency of 500kHz. It supports internal or external compensation and soft-start options, minimizing external component requirements.

 

This regulator is available in a compact 4mmx3mm DFN plastic package, suitable for surface mounting. It operates within a temperature range of -40°C to 125°C, making it robust for industrial, battery, and FPGA power applications.

 

Key features include synchronous operation for high efficiency, integrated FETs, selectable PFM/PWM modes, and adjustable switching frequency. The part also offers power-good and enable functions.
