SD1003

SD1003 1200mA, 30V Synchronous Rectified Step-Down Converter FEATURES  8V to 30V operating input range  1200mA output current  Up to 92% efficiency  High efficiency (>80%) at light load  Internal Soft-Start  400kHz switching frequency  CC/CV control mode  Input under voltage lockout  Input over voltage lockout  Start-up current run-away protection  Short circuit protection  Thermal protection  4000V ESD DESCRIPTION The SD1003 is a CC/CV control mode monolithic buck switching regulator. Operating with an input range of 8-30V, the SD1003 delivers 1200mA of continuous output current, It adopts NMOS for the main switch and PMOS for the synchronous switch. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load transient response and cycle-by-cycle curren...
