Product Overview

TPS54061EVM-142 is an evaluation module used to evaluate TPS54061, a 60V, 200mA, synchronous step down DC to 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 90µA. 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 startup ramp is controlled by the internal slow start time. The adjustable switching frequency range allows efficiency and external component size to be optimized. Frequency foldback and thermal shutdown protects the part during an overload condition.
