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 TPS92513/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 adjustabl...
