6A, 23V, 500kHz, ACOT® Synchronous Buck Converter

RT6230

Update Alert Share

The RT6230 is a synchronous Buck converter with Advanced Constant On-Time (ACOT®) mode control, which provides a very fast transient response with no external compensators. The RT6230 operates from 6V to 23V input voltage, and provides complete protection functions including over-current protection (OCP), under-voltage protection (UVP) and over-voltage protection (OVP). This IC also provides a 1.5ms internal soft-start function and an open-drain power good indicator.
