Product Overview
TPS562201 is a Texas Instruments synchronous step-down voltage regulator for Power Management designs requiring a regulated lower voltage rail from a 4.5 V to 17 V supply input. The converter is rated for 2 A output current and provides an adjustable 0.76 V to 7 V output range.
The regulator uses D-CAP2 control, supporting fast transient response with no external compensation required. Light-load operation uses pulse-skip mode. At VIN = 12 V, VO = 3.3 V, and IO = 1 A, the listed switching frequency is 580 kHz.
The device is supplied in a DDC 6-pin SOT package measuring 1.6 mm x 2.9 mm. Assembly-related facts include a 0.1 µF capacitor connected between VBST and SW pins, along with package thermal metrics such as 90.8°C/W junction-to-ambient thermal resistance.
Protection and operating parameters include current limit, thermal shutdown, output undervoltage protection, hiccup timing, UVLO thresholds, and a recommended operating junction temperature range of -40°C to 125°C.
