5A step-down (buck) current regulators with an integrated MOSFET to drive high current LEDs.
Available with 42 V and 60 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 TPS92512/HV LED drivers feature separate inputs for analog and pulse width modulation (PWM) dimming for no compromise brightness control achieving contrast ratios of greater than 10:1 and greater than 100:1, respectively.
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 300 mV using the IADJ input with an external 0 V to 1.
8 V signal.
For multi-string applications using two or more TPS92512/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 start/stop ...
