DESCRIPTION
The TP3322 is a 350KHz fixed frequency synchronous current mode buck regulator. The device integrates both 130mΩ high-side switch and 130mΩ low-side switch that provide 2A of continuous load current over a wide operating input voltage of 4.75V to 23V.The internal synchronous power switch increases efficiency and eliminates the need for an external Schottky diode. Current mode control provides fast transient response and cycle-by-cycle current limit.
The TP3322 features short circuit and thermal protection circuits to increase system reliability. Externally programmable soft-start allows for proper power on sequencing with respect to other power supllies and avoids input inrush current during startup. In shutdown mode, the supply current drops below 1μA. The TP3322 is available in SOP-8 package with the exposed pad.
