2017年1月25日 · The Maxim ICL7135 is a high precision monolithic 41/2 digit A/D converter. Dual slope conversion reliability is combined with ±1 in 20,000 count accuracy and a 2.0000V full scale capability. It features high impedance differential inputs, nearly ideal differential linearity, true ratiometric operation, auto zero and auto-polarity.

The AMC7135 is a low dropout current regulator rated for 350mA constant sink current. The low quiescent current and low dropout voltage is achieved by advanced Bi-CMOS process. 350mA …

2013年3月24日 · This How-To will show how I add AMC7135 current regulator chips to a flashlight driver board. Our desire to do this is to increase the output current to the emitter.

Linear (generally 7135 based) drivers are great for when your input and output voltage are closely matched, but you want to be able to limit current and have some level of regulation. For example, to run an XM-L2 from a single lithium-ion cell at 3A, a …

2013年1月10日 · AMC7135 is a current regulator. It supplies 350mA per chip as long as the input and output voltage is within the specified range. If a driver has 8 AMC7135 chips, it will supply constant 2800mA to the LED for as long as the battery can supply it.

By default, the qlite driver comes with 8*380mA 7135 chips. You can increase or decrease the output current by adding or removing 7135 chips, each chip adds or subtracts around .380mA. These chips are available as an add on for DIY or offer them pre …

By default, the 22mm 7135 driver comes with 16*380mA 7135 chips. You can decrease the output current by removing 7135 chips, each chip removed subtracts around 380mA. Features: *Input voltage: 2.8V - 4.5V. *Default Current: 6A (without removing any 7135 chips) *Constant current. *PCB diameter: 22mm. *PCB thickness: 1.6mm. *Components height: 4.7mm.

2009年11月3日 · They act like a variable resistor trying to keep the current at 350ma constant. As the voltage gets above the led vf any of the extra voltage gets used up as heat in the 7135. So the more voltage above the load voltage will give you more heat and less efficiency. The closer you keep the supply voltage to the load voltage the more efficient.

The TC7135 from Microchip Technology is a 4-1/2 digit Analog-to-Digital converter (ADC) which can easily provide both of these functions. The TC7135’s multiplexed BCD outputs interface easily to low cost LED or LCD decoder/drivers, such as the TC7211A. Also, the TC7135’s data outputs simplify computer interfacing.

2021年5月15日 · Replace the AMC7135 constant current 1 watt LED driver IC with something more efficient with PWM brightness control.
