BL9384

BL9384 3A, 18V High Efficiency Synchronous Step-Down Converter DESCRIPTION The BL9384 is a wide input range, highefficiency, DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. Current mode PWM control allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. On top of the integrated internal synchronous rectifier that eliminates external Schottky diode, Overall BL9384 is a highly efficient and robust solution for DC-DC step-down applications that requires wide input ranges. BL9384 is available ESOP8 Packages. FEATURES Wide Input Operating Range from 4.5V to 18V Capable of Delivering 3A No External Schottky Diode Needed Current Mode control 0.923V Reference for Low Output voltages Logic Control Shutdown Thermal shutdown and UVLO Available in ESOP8 Package APPLICATIONS LCD TVs Notebook computers FPGA power supplies LED drivers TYPICAL APPLICATION PIN OUT www.belling.com.cn 1 BL9384 MARK and ORDERING INFORMATION Mark Explanation XX: Year YY: Week ZZ: Internal code PINOUT DESCRIPTION PIN # 1 2 3 4 5 6 7 8 NAME BST IN SW GND FB COMP EN SS DESCRIPTION Bootstrap pin.
