Product Overview
The TPS54061 is a Texas Instruments synchronous step-down DC-DC converter for Power_Management designs requiring conversion from a 4.7 to 60 V input range to regulated low-current outputs up to 200 mA. It uses current-mode control with a COMP-to-switch-current transconductance of 1.0 A/V and a 0.8 V voltage reference specified across operating conditions.
Frequency control is provided through the RT/CLK pin. RT mode supports 50 to 1100 kHz operation, and external synchronization through the PLL is specified from 300 to 1100 kHz. With RRT/CLK = 120 kΩ, the switching frequency is specified at 425 kHz minimum, 472 kHz typical, and 520 kHz maximum.
The device is supplied in a thermally enhanced VSON-8, 3.00 mm x 3.00 mm package with thermal pad. Thermal data for the DRB 8-pin package includes 42.9°C/W junction-to-ambient resistance and 3.0°C/W junction-to-case bottom resistance. Protection and startup-related parameters include 4.5 V VIN start voltage, 2.9 V BOOT-PH UVLO, 2.36 ms internal slow start, and 176°C thermal shutdown.
