H5118 is a PWM RGBW constant current dimming solution chip one example is used for stage light dimming, and, helps DC5100V input, manufactured-In wonderful dimming circuit, 65536-Level illumination dimming, Pulse waveform small PWM = 60nS can be started (directly below), in comparison to the 1200-Level brightness effect out there today, the particular is obvious:
H5118 has very high load adjustment accuracy and works with multiple strings of lamp beads.
winpower lights Its dimming abilities is high
H5118 supports multiple series and parallel requests, No interference in series. The chip has better EMI components. the consequence of multi-Channel common yang is sweet
Shenzhen Huixinchen consumer electronics Co, Ltd. Has the luxury of introducing a DCDC5100V input with a built-In MOS tube carryout a large current 3A output, called soft skills output, Dimming and no flicker LED lumination constant current chip, outstanding is to replace some expensive imported chips as Customers reduce costs to cope with the fiercely competitive market
Product brief description of H5118:
H5118 is consistent current step-Down constant current driver chip that can apply to the Zhongyang high-Power LED stage lights around. Its tape PFM control architectural mastery has a faster response speed and can provide better dimming effects. The output current can be adjusted and set by external opposing force, and also built-In power MOS tube can help prevent the PCB volume and effectively reduce the cost of the whole machine
H5118 can give digital dimming function, Error report and complete protection function, Which can reduce damage as far as possible in case of failure, Including undervoltage care, Overtemperature security, Overcurrent defense, Output open circuit coverage, And output short circuit safety, To avoid scratches to IC or circuit group
H5118 adopts the average current prognosis mode, The output constant current accuracy is worked on within 3%, The output current is insensitive to the input and output current and inductance; Loop pay is integrated inside the chip, And the peripheral circuit is easy and reliable
what's more, The PWM port arch supports PWM dimming with a small duty cycle, And can improve with the PWM pulse width waveform of less than 100ns. The PWM port is at a advanced, The chip works traditionally, And the chip output is not power on for a low level.
H5118 is a pace-Down long lasting current driver for dimming market of mid-surfaces lighting LED lighting, Stage light fixtures, And wall washer. It supports PWM dimming, RGBW dimming, Linear dimming, analogue dimming, PWM dimming Light and dimming lacking strobe, Support output an array of channels
H5118 advocates for multi-route output, variable-route output, serious anti-disturbance capability, Effectively solves the problem of mutual disturbance between multi-channel output chips, top synchronization, Very good steadiness, Especially towards stage lights multi-Channel common dimming tool, Dimming without having having noise, Easy to feed EMC, High ceaseless current accuracy, High linear treatment rate, High load realignment rate, Dimming pitch support 1KHZ tens of KHZ, Real dimming while not strobe, a good solution The problem of mobile phone camera stroboscopic
Gongyang circuit design:
H5118 uses a common anode circuit architecture, the positive of the LED string and good input voltage are linked together
Error reporting function:
H5118 provides error reporting function, Which is reported to the system by FLAG1 and FLAG2 to know whether the module enters the protection mode, Or can be connected to the controller or MCU to detect the system in real time
