TPS54061 Step-Down DC-DC Converter



Texas Instruments' wide input 60 V, 200 mA converter with Low IQ


Texas Instruments TPS54061 Step-Down DC-DC Converter Texas Instruments' TPS54061 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, shutdown supply current is reduced to 1.4 µA. 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 4.5 V, but can be increased using two resistors on the enable pin.   TPS54061 Datasheet
