EG5101 is a high-performance synchronous step-down control chip based on digital algorithm current mode control. It is packaged in TSSOP-24 and is suitable for various applications that require efficient and stable step-down, such as battery chargers, electric vehicle converters, LED lamp drivers, industrial power supplies, etc. When used with Yijing Micro's high-voltage half-bridge driver chip, it can achieve applications with a maximum input of 600V. Through dual-mode modulation of PWM and COT, it can achieve wide-range output applications with a high input/output voltage ratio and low voltage drop.
