The TPS54061DRBT is a 60V/200mA synchronous Step-down DC-DC Converter with integrated high-side and low-side MOSFETs. Current mode control provides simple external compensation and flexible component selection. The non-switching supply current is 90 μA. Using the enable pin, shutdown supply current is reduced to 1.4μA. To increase light load efficiency the low-side MOSFET emulates a diode when the inductor current reaches zero. Under-voltage lockout is internally set at 4.5V, but can be increased using two resistors on the enable pin. The output voltage start-up ramp is controlled by the internal slow-start time.
