The LT3496EFE#TRPBF is a highly efficient, 4-channel, step-up LED driver. This device, engineered by Linear Technology, is especially suitable for applications that require multiple LED outputs and, in particular, ultra-low standby power. Part of the Power Management IC (PMIC) – LED Drivers category, the LT3496EFE#TRPBF enables LED supply regulation for 1 to 4 LED series strings with up to 30V output, depending on the number of LED series strings used. Due to its excellent features and performance, it is also suitable for other applications such as DC/DC LED strings, UV LED irradiators, automotive LED lights, and LED indicators.

The LT3496EFE#TRPBF incorporates a high-efficiency step-up converter, which consists of two synchronous buck/boost converter stages. The first buck/boost converter takes the input voltage, which can be as low as 2.5V, and boosts it to approximately 3.2V. This output supplies a second step-up converter, which boosts the voltage to an adjustable level up to 30V. The combination of these two converters allows the LT3496 to provide adjustable outputs with an extremely low quiescent current, ideal for devices that need to operate in low standby power conditions.

The LT3496EFE#TRPBF has on-chip power monitoring, temperature monitoring, voltage clamping, current limit, and thermal shutdown protection (OTP), which provide a comprehensive set of safety features. Similarly, it boasts a wide frequency range of 100kHz to 2MHz and an adjustable valley current control scheme which allows for further flexibility in LED lighting applications. The adjustable valley current also allows for optimal component selection, allowing the use of lower cost components in the LED lighting design. The device is offered in an MSOP-8 package for ease of design.

The LT3496EFE#TRPBF uses an external N-channel power MOSFET for each converter, which limits the maximum output current and helps to reduce power dissipation. The device also features Logic-controlled external power MOSFETs which can be used to control the output current of each converter. This provides excellent efficiency and ensures minimal hot-spot temperatures, making it an ideal choice for high-efficiency LED lighting applications that require a wide variety of output currents.

Overall, the LT3496EFE#TRPBF is an ideal solution for a wide variety of applications that require ultra-low standby power and adjustable outputs, such as LED lighting, DC8DC LED strings, and UV LED irradiators, among others. Its adjustable valley current control scheme, on-chip protection features, and Logic-controlled external power MOSFETs enable excellent performance and excellent efficiency for low-power systems. Thanks to its small MSOP-8 package, the device is easy to design into even the space-constrained systems. Therefore, it is an excellent choice for many applications.
