TPS54200/TPS54201 Synchronous Buck LED Drivers Texas Instruments TPS54200/TPS54201 Synchronous Buck LED Drivers are 1.5A synchronous buck WLED drivers with 28V maximum input voltage. Current mode operation provides fast transient response and eases loop stabilisation. By integrating the MOSFETs and employing the SOT23-6 package, TPS54200/TPS54201 achieves high power density and offers a small footprint on the PCB. The TPS54200/TPS54201 implements analogue dimming by changing internal reference voltage proportional to the duty cycle of PWM signal input in analogue dimming mode. This device also supports PWM dimming mode, in which the internal reference voltage is halved to 100mV for higher efficiency. Cycle-by-cycle current limit in high-side MOSFET protects the converter in an overload condition and is enhanced by a low-side MOSFET freewheeling current limit which prevents current runaway. There is a low-side MOSFET sinking current limit to prevent excessive reverse current.Learn more
