RT6230

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

General Description

Features

^6V to 23V Input Voltage Range

^Adjustable from 5V to 12V Output Range

^500kHz Switching Frequency

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.

^ACOT Mode Performs Fast Transient Response

^Integrated MOSFETs

^31mΩ of High-Side MOSFET

^20mΩ of Low-Side MOSFET

^Supports MLCC Output Capacitors

^Internal Soft-Start (1.5ms typ)

^Built-in OVP/UVP/OCP

^Power Good Indicator
