HSY8120B1ABC Synchronous Step-Down Converter
■HSY8120B1ABC is awide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 2A of output current. With a fixed switching frequency of 500KHz, this current mode PWM controlled converter allowsthe use ofsmall external components,suchas ceramic input and output caps, as well as small inductors.
■HSY8120B1ABC 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 op eration.An OVP function protects the IC itself and its downstream system against input voltage surges. With this OVP function, the IC can stand off input voltage as high as 19V, making it an ideal solution for industrial applicationssuch as LCDTV, Set Top Box,Portable TV, etc.
■HSY8120B1ABC is available in SOT-23-6L package.
