The SCT2A11 is 0.6A synonous buck converters with wide input voltage, ranging from 4.5V to 100V, which integrates an 750mΩ high-side MOSFET a 500mΩ low-side MOSFET. The SCT2A11, adopting the constant-on time (COT) mode control, supports the Force Pulse Width Modulation (FPWM) Mode to achieve the small output ripple at light load condition.The SCT2A11 features programmable switching frequency from 300 kHz to 800kHz, which provides the flexibility to optimize either efficiency or external component size. The SCT2A11 offers cycle-by-cycle current limit hiccup over current protection, thermal shutdown protection, output over-voltage protection input voltage under-voltage protection. The device is available in an 8-pin thermally enhanced SOP-8 package.

Application:

• Power garden Tools, E-Bike, E-scooter
• High-cell-count battery packs 
• Industry telecom System
