TPS545192.95V to 6V Input, 5A Synchronous Step-Down Converter | Voltage Regulators - DC DC Switching Regulators | 2 | Active | The TPS54519 device is a full featured 6 V, 5 A, synchronous step down current mode converter with two integrated MOSFETs.
The TPS54519 enables small designs by integrating the MOSFETs, implementing current mode control to reduce external component count, reducing inductor size by enabling up to 2 MHz switching frequency, and minimizing the IC footprint with a small 3mm × 3mm thermally enhanced QFN package.
Efficiency is maximized through the integrated 30mΩ MOSFETs and 350µA typical supply current. Using the enable pin, shutdown supply current is reduced to 2 µA by entering a shutdown mode.
Under voltage lockout is internally set at 2.6 V, but can be increased by programming the threshold with a resistor network on the enable pin. The output voltage startup ramp is controlled by the slow start pin. An open drain power good signal indicates the output is within 93% to 107% of its nominal voltage.
Frequency fold back and thermal shutdown protects the device during an overcurrent condition.
The TPS54519 is supported in the SwitcherPro Software Tool atwww.ti.com/switcherpro.

TPS5452117V Input, 5A Synchronous Step-Down Converter | DC/DC & AC/DC (Off-Line) SMPS Evaluation Boards | 3 | Active | The TPS54521 is a full featured 17V, 5A synchronous step down converter which is optimized for small designs through high efficiency and integrated high-side and low-side MOSFETs. Further space savings are achieved through current mode control, which reduces component count, and by selecting a high switching frequency, reducing the inductor’s footprint.
The output voltage startup ramp is controlled by the SS/TR pin which allows operation as either a stand alone power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and the open drain power good pins.
Cycle by cycle current limiting on the high-side FET protects the device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. Hiccup protection will be triggered if the overcurrent condition has persisted for longer than the preset time. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature. The TPS54521 is available in a 14 pin, 3.5mm × 3.5mm QFN, thermally enhanced package.
