DESCRJPTION :3A同步高压降压DC-DC
The TP3320 is a 500KHz fixed frequency synchronous current mode buck regulator. The device integrates both 135m? high-side switch and 90m ? low-side switch that provide 3A of continuous load current over a wide operating input voltage of 4.5V to 28V. 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 TP3320 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 dropsbelow 1µA.TheTP3320isavailable in SOP-8 package with the exposed pad.
