Deion:

The SCT2A22 is 1A synonous buck converter with wide input voltage, ranging from 4.5V to 100V,which integrates an 530mΩ high-side MOSFET a 220mΩ low-side MOSFET. The SCT2A22, adopting the constant-on time (COT) mode control, supports the Forced PWM mode to achieve smaller output ripple support Isolation buck topology.The SCT2A22 features programmable switching frequency from 100 kHz to 600KHz with an external resistor, which provides the flexibility to optimize either efficiency or external component size.The SCT2A22 offers cycle-by-cycle current limit,thermal shutdown protection, output over-voltage protection input voltage under-voltage protection.The device is available in an 8-pin thermally enhancedSOP-8 package..

Application:

• E-Bike, E-scooter
• 48V Industry Power Bus System 
• BMS
