AR2003FV-13 is a kind of Power Supply Controllers, Monitors (PMIC) developed by Renesas Electronics America Inc., that are mainly used in step-down converter applications. It is a down-programmable switch-mode power supply (SMPS) controller which provides electronics industries a way of providing power with exceptional accuracy and efficiency.

Introduction

AR2003FV-13 is a PMIC specifically designed for SMPS applications such as AC-DC and DC-DC converters. It is an ideal solution for providing ultra-low power and high accuracy power conversions. It features a high frequency PWM switching regulator operation that is able to support pulse width modulation frequencies of up to 3MHz. With its low voltage operation, it offers very low-power dissipation, especially when running at 3MHz. Furthermore, it provides the designer with high flexibility and ease of use due to its embedded on-board digital configurability.

Application fields

The AR2003FV-13 PMIC can support various step-down converter applications such as voltage supply, regulation and switch-mode converters. It is mainly used in applications that require low power dissipation and high accuracy power conversions. Some of its most common applications include battery management systems, telecom base stations and automotive applications. In addition, it can be used in solar microinverters, motor control centric applications, motor drives and any other applications that require low power dissipation and high accuracy power conversions.

Working Principle

The AR2003FV-13 is a PWM step-down controller that is designed to generate pulse width modulated (PWM) waveforms for both single and dual output digital supply applications. It features a zero voltage switching (ZVS) based average current mode control (ACM) architecture that provides excellent dynamic performance, high efficiency, low power losses and fast transient responses. The output of the controller is generally determined by the value of an external reference voltage as well as the values of certain external resistors. It also works in conjunction with an external driver to provide pulse-width\'s modulated (PWM) waveforms to drive power switches. This is done to enable the step-down converter to operate in DCM (Discontinuous Conduction Mode) for steady-state operation and to switch to CCM (Continuous Conduction Mode) when the output load demand increases. The powerful pulse-width modulated control in the AR2003FV-13 makes it an ideal choice for a wide range of switch mode power supply applications.
