The RT6206A is a synchronous step-down DC/DC converter
with Advanced Constant On-Time (ACOTTM) mode control.
It achieves high power density to deliver up to 5.5A output
current from a 4.5V to 18V input supply. The proprietary
ACOTTM mode offers an optimal transient response over a
wide range of loads and all kinds of ceramic capacitors,
which allows the device to adopt very low ESR output
capacitor for ensuring performance stabilization. In
addition, RT6206A keeps an excellent constant switching
frequency under line and load variation and the integrated
synchronous power switches with the ACOTTM mode
operation provides high efficiency in whole output current
load range. Cycle-by-cycle current limit provides an
accurate protection by a valley detection of low side
MOSFET and external soft-start setting eliminates input
current surge during startup. Protection functions include
thermal shutdown for RT6206A. RT6206AHGSP RT6206AHGQW RT6206ALGCP资料下载
