Power Management Integrated Circuits (PMICs) are a combination of various functions that provide a general purpose of controlling power to electronic systems. PMICs typically include controllers, regulators, switches, multiplexers and reference voltage generators. There are various types of PMICs including Linear, Switching, Battery Management, Motor Controllers and LED Drivers. PMICs are an essential part of many portable electronic devices and are widely used in the industry.

LED Drivers are a type of specialized PMICs that are specifically designed to provide power to an LED (Light Emitting Diode) light source. LED Drivers offer the capability to accurately adjust the current and voltage to match the individual requirements of the LED, providing a consistent level of light output and long life to the LED. LEDs are widely used in a variety of applications, from automotive and household lighting to industrial, medical and safety lighting.

The LM3210EUD-2#TRPBF is an LED Driver particularly tailored to automotive and industrial LED applications. It is a 40V LED Driver that offers an adjustable LED current up to 300mA, making it ideal for applications requiring higher LED outputs. It is designed to be used in a wide range of operating conditions, from -40°C up to +105°C ambient temperature. It features both pulse-by-pulse current mitigation and pre-thermaldriver shutdown protection.

In addition to its maximum LED current, the LM3210EUD-2#TRPBF offers a wide range of output current settings from 2.5mA up to the absolute maximum limit. This allows for the adjustment of light intensity to achieve the desired level for a particular application. It offers high efficiency with a maximum current efficiency of 95%.

In terms of working principle, the LM3210EUD-2#TRPBF relies on a fixed frequency, constant-off-time (COT) PWM control scheme. An internal logic block provides a stable, PWM output based on the current setpoint. The COT technique eliminates the need for an external current-sensing circuit, aiding in the design and reducing part count. The PWM signal is supplied to the OEM to control the LED brightness.

The LM3210EUD-2#TRPBF is a highly integrated PWM LED driver solution that is suitable for automotive, industrial and general-purpose LED applications. It provides power efficient control and high reliability at wide range of operating conditions. It is suitable for a wide range of LED applications and with its high accuracy and reliable pulse-by-pulse current mitigation it can provide long lifetime lighting for a wide range of applications.
