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.

The TPS54200 and TPS54201 can be used to drive single-string or multi-string mono-color or Infrared (IR) LED arrays as in the case of night vision cameras.

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.

Cycle-by-cycle current limit in the 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. For safety and protection, the TPS54200 and TPS54201 devices include LED-open and -short protection, sense-resistor-open and -short protection, and device thermal protection. The TPS54200 device implements shutdown-and-latch mode protection, whereas the TPS54201 device adopts auto-retry mode protection.
