RT8279GSP Richtek HV BUCK

RT8279GSP, DC-DC Switching Buck Step Down Regulator, Adjustable, 5.5V-36Vin, 1.2V-26Vout,5Aout, 500kHz, SOP-8

The RT8279GSP is a 500 kHz step-down regulator with an internal power MOSFET achieving 5A of continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. For protection, the RT8279GSP provides cycle-by-cycle current limiting and thermal shutdown protection. An adjustable soft-start reduces the stress on the input source at startup. In shutdown mode, the regulator draws only 25μA of supply current.

The RT8279GSP requires a minimum number of readily available external components thus allowing designing compact solutions at 85%+ efficiency. The RT8279GSP is available in the 5 x 4 mm SOP-8 (Exposed Pad) package.
