Texas Instruments TPS92200 1.5A Synchronous Buck LED Driver comes with a 30V maximum input voltage. By integrating the high-side and low-side NMOS switches, the TPS92200 device provides high power density with high efficiency in an ultra-small solution size. The Texas Instruments TPS92200 uses peak-current-mode control and full internal compensation to provide high transient response performance over a wide range of operating conditions.
The TPS92200 device supports flexible dimming methods. TPS92200D1 implements both PWM and analog dimming modes. In PWM dimming mode, LEDs will be turned on and off according to the PWM duty cycle periodically. Its analog dimming mode is achieved by changing the internal reference voltage proportional to the voltage level of the analog input in a 5% to 100% range. TPS92200D2 implements deeper analog dimming by changing the internal reference voltage proportional to the duty cycle of the PWM signal input in a 1% to 100% range.
For safety and protection, the TPS92200 devices implement full protections include LED open, LED+ short to GND, LED short, sense resistor open and short, and device thermal protection.
