HV3101E22-22S

The HV3101E22-22S is from NXP’s product portfolio of scalable flood-light product with leading performance. This device features peak current up to 3.5A and a wide input voltage range of 8V to 75V. It also has configurable output current limit, output voltage limit, under voltage lockout, short-circuit protection, over-temperature protection and adjustable current-limit slope. The HV3101E22-22S offers excellent robustness, very low ripple and low electromagnetic interference (EMI).

HV3101E22-22S has a variety of applications and is broadly suitable for driving flood-light, street lighting, landscape lighting, signboard lighting and other lighting applications. It provides end users with high quality solutions that allow them to consume less energy, emitting a comfortable light and integrating into existing lighting networks. Moreover, HV3101E22-22S is well suited for LED lighting products which are distributed via the main power grid that is very important for street lighting and residential luminaries applications.

The working principle of the HV3101E22-22S can be described as follows. First, the input current is rectified and fed to the avalanche breakdown diode which experiences a high voltage at the turn-on. Then, an avalanche breakdown diode provides a current limit for the output current when the voltage exceeds the turn-on point and a transient protection device is triggered. Finally, the output current is provided by a high-side and a low-side switch combination which provides current sense and smooth dimming control.

HV3101E22-22S is a powerful device with scalability and great performance. It enables lighting systems to realize efficiency goals with low cost while still providing robust design with reliable performance. Its high efficiency and low EMI are very attractive features which pave the way for high brightness, low power consumption and clean light output. Furthermore, its low component count, variability of input voltage and very low ripple are also important which assists HV3101E22-22S to be the ideal choice for LED light solutions.
