FAN23SV06MPX

FAN23SV06 is a highly efficient integrated synchronous buck regulator. This device utilize Fairchild's constant on-time control architecture to provide excellent transient response and to maintain a relatively constant switching frequency. It utilizes pulse frequency modulation mode to maximize light-load efficiency by reducing switching frequency when the inductor is operating in discontinuous conduction mode at light loads. Switching frequency and overcurrent protection can be programmed to provide a flexible solution for various applications. Output overvoltage, undervoltage, overcurrent and thermal shutdown protections help prevent damage to the device during fault conditions. It operate from a 5V rail (±10%) if VIN/PVIN/PVCC are connected together to bypass the internal linear regulator. Some applications are service/desktop computers, NVDC notebooks/netbooks, game consoles, telecommunications, storage.
