The TPS54200 and TPS54201 devices are 1.5-A synchronous buck mono-color or IR drivers with 28-V maximum input voltage. Current-mode operation provides fast transient response and eases loop stabilization.
By integrating the MOSFETs and employing the SOT-23-THIN package, the TPS54200 and TPS54201 devices provide high power density and only require a small footprint on the PCB.
The TPS54200 and TPS54201 devices implement analog dimming by changing the internal reference voltage proportional to the duty cycle of the PWM signal input in analog dimming mode. This devices also support PWM dimming mode, in which the internal reference voltage is halved to 100 mV for higher efficiency.
