TPS54061DRBT Description
The TPS54061DRBT is a step-down (buck) regulator with integrated high-side and low-side n-channel MOSFETs that operates at 60 volts and 200 milliamperes. To increase performance during line and load transients, the device employs constant frequency, current-mode control, which decreases output capacitance and simplifies the design of external frequency compensation.
When selecting the output filter components, the switching frequency of 50 kHz to 1100 kHz enables for efficiency and size optimization. The switching frequency is controlled via a resistor-to-ground connection on the RT/CLK pin. On the RT/CLK pin, the device features an inbuilt phase-lock loop (PLL) that is used to synchronize the power switch turn on to a falling edge of an external system clock.
