Description

The TPS92513DGQT is a 1.5A step-down (buck) Current Regulator with an integrated MOSFET to drive high current LEDs. This LED driver operates at user selected fixed-frequency with peak-current mode control and delivers excellent line and load regulation. The LED driver features separate inputs for analogue 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. For multi-string applications using two or more 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.
Dedicated PWM dimming input
Adjustable under-voltage lockout
Overcurrent protection
Over-temperature protection
Integrated 220mR high-side MOSFET
±5% LED Current accuracy
