Intel Corporation Voltage Regulators - DC DC Switching Regulators ER3110DI

The ER3110DI is a synchronous buck regulator designed to deliver up to 1A of output current with an input voltage range of 3V to 36V. It features integrated high-side and low-side NMOS FETs, which contribute to its high efficiency and low component count. The regulator operates in either Pulse Frequency Modulation (PFM) mode for improved efficiency at light loads or can be switched to forced Pulse Width Modulation (PWM) mode. The default switching frequency is set at 500kHz but can be adjusted from 300kHz to 2MHz using an external resistor. This device supports both internal and external compensation, allowing for flexibility in design. It is suitable for a variety of applications, including industrial control, medical devices, and portable instrumentation. The ER3110DI is housed in a compact 4mm x 3mm DFN package and operates over an industrial temperature range of -40¬8C to +125¬8C. Its minimal external component requirement simplifies the design process, making it a robust choice for high voltage and battery-powered applications.
