LED drivers are widely used in the world and they are becoming more and more prevalent in the modern world. LED drivers are employed in many different applications and industries across the world, from automotive lighting to medical lighting. The TPS61162AYFFR is a single-channel switching LED driver IC (Integrated Circuit) that supports up to 2A of output current and up to 1A of input current. It is designed for high efficiency applications, such as ceiling lamps and downlights, where current consumption and reliability are important.

This device is a current-mode driver IC, meaning it relies on current output rather than voltage. The TPS61162AYFFR operates with Power Factor Correction (PFC), whereby it operates at a near constant input current to minimize current ripple, improve power factor, and reduce stand-by power consumption. It features a wide range of input voltages and output currents, enabling designers to create cost effective and efficient lighting designs with minimal component counts.

The TPS61162AYFFR is composed of an input voltage regulator, a voltage mode MOSFET controller, and a dual active-low power MOSFET. It provides a constant output current over a wide range of input voltages and LED strings. The LED driver has a wide input voltage range from 5.8V to 100V, and it can operate with a wide dimming range from 0.125uA to 2A, making it suitable for numerous lighting applications. The device is designed to provide a high power efficiency of up to 97%, and it is also designed to protect from EMI (Electro Magnetic Interference).

The device has a maximum switching frequency of 600kHz and a low standby current of under 0.1μA. It also offers selectable burstmode frequency and a soft start for a smooth dimming ramp. The TPS61162AYFFR is housed in a 10-lead (2 x 5) MLPQ package, making it easy to mount and integrate into end products.

The TPS61162AYFFR is well-suited for a variety of lighting applications, including residential and commercial lighting, downlights, cove lighting, panel lights, architectural lighting and decorative lighting applications. The TPS61162AYFFR is a versatile, high efficiency and reliable LED driver choice that is ideal for both low and high power applications.
