SCT2A22STER

Voltage Regulators - DC DC Switching Regulators Overview

The SCT2A22STER is a synchronous buck converter from Silicon Content Technology with a 4.5V to 100V input range and 1.2A continuous output current. It integrates a 530mΩ high-side and 220mΩ low-side MOSFET. The device uses constant-on-time control with forced PWM mode for isolation topologies. Key parameters include a 1.2V ±1% feedback reference, 4.3ms soft-start, and programmable switching frequency from 100kHz to 600kHz. It features cycle-by-cycle current limit, over-voltage protection, and under-voltage lockout in an ESOP-8 package.
