The LT1932ES6#TRPBF is a high performance PMIC - LED driver and a switch-mode current control device in one package. It is designed for driving 12V and low voltage LEDs, such as white LEDs. The LT1932ES6#TRPBF provides precise current and accurate power delivery to each LED. It can also be used in a PWM-controlled dimming system, allowing precise and dynamic illumination control.

The application field of LT1932ES6#TRPBF includes lighting control, automotive lighting, industrial lighting, and more. It is suitable for general power-efficient applications such as post-top lighting, streetlighting and tunnel lighting where the lights are operating in harsh environments. It is also suitable for lighting applications used in outdoor, commercial and residential environments where accurate light control and power efficiency is required.

The LT1932ES6#TRPBF is designed to produce precise and low noise current. It employs a constant current switch-mode control scheme to ensure the controller runs in a current mode and is capable of driving the LED load with a fast settling time. The LED drive current is set by an external resistor. The LED current is then regulated to within +/-1% of the LED setpoint voltage.

The LT1932ES6#TRPBF also has built-in power sense and temperature sense circuits, which enable the device to detect both the LED load current and temperature, thus providing accurate and stable current control. The power sense circuit monitors the LED current and provides feedback to the controller within the device, allowing it to adjust the LED drive current based on the input voltage. This helps to ensure the LED current is maintained precisely while reducing power dissipation.

The LT1932ES6#TRPBF features excellent EMI/RFI immunity and power supply filtering capability. It offers effective filtering to eliminate electrical noise generated in both the input and output of the device. The power supply filter also helps reduce the ripple voltages on the power supply and ensure a clean current drive.

The LT1932ES6#TRPBF offers up to 80% efficiency. The device has a wide input voltage range from 4.5V to 40V, making it suitable for a variety of applications. It is capable of driving the LED load from a constant current of up to 2A. The LT1932ES6#TRPBF also has an external enable pin, which makes it possible to enable/disable the device and also to provide enable/disable signalling for other devices within the system.

The device is available in a small TSSOP-14 package and has an operating temperature range of -40°C to +85°C. The LT1932ES6#TRPBF is a highly efficient, robust and cost-effective PMIC - LED driver, which is suitable for applications requiring precise current drive and high efficiency.
