The TPS56921PWPR is a synchronous step-down converter designed for input voltages ranging from 4.5V to 17V and capable of delivering up to 9A of output current. It features integrated high-side and low-side MOSFETs with on-resistances of 26m,Ѷ and 19m,Ѷ, respectively, which contribute to its efficiency in compact designs. The device supports VID control via an I¬=C-compatible interface, allowing for adjustable output voltage in 10mV steps from 0.72V to 1.48V. Protection features include overcurrent protection with hiccup mode, thermal shutdown, and adjustable soft start to manage inrush current. The TPS56921 operates over a junction temperature range of -40¬8C to 125¬8C and is housed in a 20-pin HTSSOP package. Its switching frequency can be set between 200kHz and 1.6MHz, providing flexibility for various applications, including digital TVs, set-top boxes, and power distribution systems. The device also includes a power good monitor for under- and over-voltage conditions.
