TPS9. 25. 13 1. 5 A Buck LED Driver with Integrated Analog Current Adjust The TPS9. HV are 1. 5. A step down buck current regulators with an integrated MOSFET to drive high current LEDs. Available with 4. V and 6. 0 V HV input ranges, these LED drivers operate at a user selected fixed frequency with peak current mode control and deliver excellent line and load regulation. The TPS9. 25. 13HV LED drivers feature separate inputs for analog and pulse width modulation PWM dimming for no compromise brightness control achieving contrast ratios of greater than 1. The PWM input is compatible with low voltage logic standards for easy interface to a broad range of microcontrollers. The analog LED current setpoint is adjustable from 0 V to 3. V using the IADJ input with an external 0 V to 1. Toca Race Driver 3 Camera Hack more. V signal. For multi string applications using two or more TPS9. Richtek/Products/ProductSpecs/RT8458/en/Version1/06064kzvcg.jpg' alt='Mosfet Pwm Led Driver' title='Mosfet Pwm Led Driver' />HV LED drivers, the internal oscillator can be overdriven by an external clock ensuring all of the converters operate at a common frequency thereby reducing the potential for beat frequencies and simplifying system EMI filtering. An adjustable input under voltage lockout UVLO with hysteresis provides flexibility in setting startstop voltages based upon supply voltage conditions. The TPS9. 25. 13includes cycle by cycle overcurrent protection and thermal shutdown protection. Cinema 4D Visualize Serial Port. It is available in a 1. HVSSOP Power. PAD package. July 2008 Rev 3 118 18 STCS2A 2 A max constant current LED driver Features Up to 40 V input voltage Less than 0. V voltage overhead Up to 2 A output current. This Instructable will show you how to built a Constant Current for high power LEDs, using only two components. High power LEDs are getting cheaper and cheaper, ho.
