The TPS54061-Q1 device is a 60-V, 200-mA, 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 reduces the shutdown supply current to 1.4 µA.
To increase light-load efficiency, the low-side MOSFET emulates a diode when the inductor current reaches zero.
The internal undervoltage lockout setting is 4.5 V, but using two resistors on the enable pin can increase the setting. The internal slow-start time controls the output-voltage start-up ramp.
The adjustable switching-frequency range allows optimization of efficiency and external component size. Frequency foldback and thermal shutdown protect the part during an overload condition.
The TPS54061-Q1 enables small designs by integrating the MOSFETs and boot recharge diode, and by minimizing the IC footprint with a small 3-mm × 3-mm thermally-enhanced SON package.
The TPS54061-Q1 is supported in the WEBENCH™ Designer at www.ti.com.
