Rich technology HB LED lighting application driven IC added a new member

Rich science and technology should be the market demand for the introduction of HB LED high quality driver IC-RT8453 simple BUCK architecture. Compared to the current hysteresis current control IC on the market, the biggest difference is that the product uses constant current power frequency control mode to enable the current accuracy can really reach + 5%, which greatly reduce the customers in the production for a number of different LED series current caused by the problem of lack of precision. The IC uses SOP-8 (Exposed Pad) package, while in the pin and peripheral devices to simplify a lot, to the customer to save unnecessary expenses. But RT8453 did not reduce the quality and performance due to the separation of other functions, RT8453 still inherits the excellent quality of the RT84 series: input wide voltage range 4.5~40V, output support to 40V/1A. The constant frequency and constant current control, the small volume and small inductance inductance can meet the design requirements, CCM mode and current slope compensation technology and use unique, so that the number of driving HB LED at the maximum allowable range of any change of the input voltage and output current remained stable, flexible application still support PWM and ANALOG dimming. Support for programmable soft start settings, independent of the EN enable side, easy to connect MCU control. Support undervoltage lockout and over temperature protection OTP function. Built in 1.5A switch, using the IC industry's most reliable bipolar process design, this IC is a real response to LED long life, high reliability and high performance requirements and the birth of high-quality devices.

This IC for the input voltage is relatively stable, only need the step-down LED drive, such as street lamp, lamp, lamp and isolated power supply daylight lamp, ceiling lamps, lamp panel, wall lamp (Fang Kuaideng) LED constant current drive and so on... The high precision constant current and high reliability can allow the LED load or input power to change in the operating range without the need to adjust or redesign the peripheral device parameters for different lamps. The inventory and purchasing lower cost manufacturers, the product development cycle shorter engineers, let the time to market of new products faster! Rich in different application of LED lighting products provide the corresponding technical support. If the sample request please contact the rich science and technology.
