Linear constant current LED flash warning light dedicated drive chip H7310 features

In the intelligent dimming and peripheral requirements, the technological development of low-voltage linear constant current chips is also followed, and in most of the low-voltage linear constant current chips, only 10W below is possible. Moreover, the dimming effect is poor. Can't do it like high-power low-voltage linear constant current chips. Samples and DEMO tests can be applied for free, free technical support. 1. Features 1: High current, high-constant accuracy, but low-voltage linear constant current chip technology different in turn, then take a look at the characteristics of low-voltage linear constant current chip H7310 with ordinary low-pressure dimming chips, It reflects which level developed to the bottom of the low-voltage linear constant current chip. The low-voltage linear constant current chip H7310 is a single-channel and supports controllable silicon tuning, intelligent dimming, low pressure dimming and other fields. The LED linear constant current drive chip of the application circuit uses Huihai semiconductor constant current control technology, and the current value can be set between 16mA to 1500 mA by an external CS resistor, and the constant current reaches ± 3%. High current, high constant current accuracy. This is one of the characteristics of the low-voltage linear constant current chip H7310, and the output current does not change the voltage of the SW outlet. The constant current performance is better, this is the embodiment of the H7310 technology. 2, Features 2: No capacitors, wide pressure 2.-85V input, the H7310 chip is simple, there is no more expensive effort when designing, in addition, the wide-pressure input voltage makes H7310 better advantage, 2.5-85V wide-pressure inputs can be supported, and the H7310 specification has a schematic diagram of the design of the H7310 typical application. At low voltage input, there is no need for a capacitor, just a resistance is needed. The circuit is simpler. 3, Features 3: The PWM frequency supports 25K, the dimming depth is 0.1%, Yi Kuihui, and smooth dimming curve. The H7310 is done in the dimming market. With Huahai Semiconductor's dimming technology, the dimming frequency of the chip is increased, and if there is no frequency flash, the dimming frequency is improved, and the effect of easy to enlightenment is also highlighted, and the high-profile frequency can be quickly enlightened. Moreover, the dimming depth can do 0.1% to mobilize the performance of the chip. The following is a dimming graph. Read more
