HM1488C Datasheet | H&M Semiconductor

DESCRIPTION 4A, 16V High Efficiency Synchronous Step-Down Converter Features The HM1488C is a wide input range, high-efficiency, DC-to- DC step-down switching regulator, capable of delivering up to 4A of output current. Current mode PWM control allows the use of small external ponents, 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, HM1488C also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. Therefore, HM1488C is a much superior solution in parison to other petitions in terms of efficiency and cost. Overall, HM1488C is a highly efficient and robust solution for DC-DC step-down applications that requires wide input ranges. - Wide Input Operating Range from 4.2V to 16V - High Efficiency: Up to 95% at Light Load - Capable of Delivering 4A - No external Schottky Diode Needed - Inductor Short Circuit Protection - 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 puters - FPGA power supplies - LED drivers The HM1488C is available in ESOP8 package.
