Introduction

The ADM660ARZ-REEL7 is a DC-DC switching regulator manufactured by Analog Devices Inc. The device is designed to provide a step-down voltage output with both current and voltage sensing feedback, providing tighter regulation and improved transient response. It is part of the Power Management Integrated Circuit (PMIC) family of products with its main application in the consumer electronics and automotive industries.

Overview

The ADM660ARZ-REEL7 is a synchronous step-down switching regulator with a power input range from 4.5V to 16V and adjustable output voltage from 0.8V up to 4.5V. It features an internal power MOSFET switch with an integrated current sensing mechanism and voltage feedback regulation loop. The MOSFET switch is capable of delivering up to 3A of output current with an efficiency up to 95%. It also offers a wide range of protection features, including thermal shutdown, over-current protection and under-voltage lockout. The device is available in a 16-lead TSOP package and is offered in commercial, industrial, and automotive temperature grades.

Working Principle

The ADM660ARZ-REEL7 works using the pulse width modulation (PWM) technique. It has an internal voltage reference and current sensing circuitry, which work together to determine the on and off times of the internal MOSFET switch. When the power supply voltage is higher than the output voltage, the MOSFET is turned on and current is provided from the input supply to the output. When the output voltage rises above the input, the MOSFET switch is turned off and the output is regulated by the feedback loop.

The voltage feedback loop ensures tight regulation of the output voltage during load transients and maintains the output voltage at a constant set level with the help of a low dropout (LDO) control scheme. An external resistor is used to set the output voltage, and the loop gain can be adjusted with the help of an external capacitor. The device also features a soft-start circuit which helps minimize the inrush current and provides stability in the system.
