Product Overview
The TPS560430 is a Texas Instruments synchronous step-down converter for Power_Management designs that require conversion from a 4 to 36 V input range to regulated lower-voltage rails. The recommended output-current range is 0 to 600 mA, and the output-voltage range is 1.0 V to 95% of VIN. Device options include PFM and FPWM operating modes, 1.1 MHz and 2.1 MHz switching-frequency versions, and a fixed 3.3 V output option.
The part is supplied in a SOT-23-6 package with a 2.90 mm x 1.60 mm body size. Package thermal data for the DBV 6-pin package includes 173 °C/W junction-to-ambient resistance, 116 °C/W junction-to-case top resistance, and 31 °C/W junction-to-case bottom resistance. Assembly and layout planning should account for the CB-to-SW bootstrap capacitor connection, specified as 100 nF.
Key operating and protection parameters include VIN UVLO thresholds, EN threshold and hysteresis values, peak and valley inductor current limits, hiccup threshold and timing, thermal shutdown at 170 °C typical, and a -40 to 125 °C recommended operating junction-temperature range.
