MAX8722CEEG+

Lighting, Ballast Controllers Overview

The MAX8722CEEG+ is a synchronous step-down switching regulator controller manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from an input voltage range of 3V to 16V and supports output voltages adjustable from 0.6V to 5.5V. The device features a fixed 400kHz switching frequency and integrates a high-side N-channel MOSFET driver with a 2A peak current capability. It includes comprehensive protection mechanisms such as cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout. The component is housed in a 28-pin QSOP package and is rated for operation within a temperature range of -40°C to +85°C.
