NXP announced the world's first integrated tunable optical power (mains) LED driver IC

NXP semiconductors (NXP Semiconductors, created by PHILPS independent semiconductor company) today announced the launch of the world's first integrated dimmable mains LED driver SSL2101. NXP SSL2101 is a small size of switch mode power supply (SMPS) controller is designed for IC, LED driver design, and provide a dimming capability, to further improve the energy efficiency of lighting LED. SSL2101 can drive a variety of different power requirements of the lighting system, including LED modified lamps, LED module, LED spotlight, spotlights and LED lights used in store display. SSL2101 with adjustable light for lighting system designers to design more energy-efficient system provides a rare opportunity. This high cost benefit ratio device has a high degree of integration, a small number of electronic components, circuit board space to maintain the smallest, while allowing designers to make full use of the advantages of LED tunable optical characteristics. En Zhipu power and lighting solutions Department Marketing Director Robert Jonge said: "de En Zhipu solutions help to provide more energy-efficient lighting products, to meet the lighting needs of the development and change of the movement and support of green lighting. SSL2101 has lower energy consumption, longer service life, smaller size and more durable". SSL2101 is fully compatible with the present lighting infrastructure, can be directly used rectifier power combining phase dimmer work. The SSL2101 contains a high voltage power supply switch that can be started directly from the rectified mains voltage, without the need for an external start circuit. In order to support dimming capability, the SSL2101 contains two integrated high voltage switches for voltage divider operation, as well as an input for induction of real time lamp power, and, when necessary, the activation of the divider. SSL2101 can also provide non isolation on a chip (Buck) and isolation (flyback) solution. It has an additional input that can be used to detect the demagnetization of the inductive element, ensuring that the magnetic material is fully utilized to prevent the current from hard switching. The built-in circuit of the device can be used to reduce the capacitive switching loss, optimize the switching efficiency of the valley bottom, so that the SSL2101 at low power levels can be efficient power conversion. SSL2101 uses the on time mode and frequency mode to control LED brightness. The combination of frequency change control and switch on time control is used to produce the light adjusting curve similar to incandescent lamp. Two. The use of the two control methods also allows the designer to reduce the peak current and help reduce the acoustic noise of transformers or inductors. This enhanced IC packages and built-in over temperature protection function by cooling (OTP) to provide safe and reliable solution. It also has short winding protection (SWP) and over current protection (OTP) functions, in line with the relevant safety and power factor requirements. 18 February - 20, NXP will be in the state of California Santa Clara Convention Center held the "lighting development strategy meeting" on the show SSL2101 IC.
