3 Description
The 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. 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.
The TPS54061 enables small designs by integrating
the MOSFETs, boot recharge diode, and minimizing
the IC footprint with a small 3.00 mm x 3.00 mm
thermally enhanced VSON package
The TPS54061 is supported in the WEBENCH™
Designer at www.ti.com.
