RT6203E
6A, 18V, 700kHz ACOTTM Synchronous Step-Down Converter
with VID Control
General Description
The RT6203E is an adaptive on-time mode synchronous
Buck converter. The main control loop of the RT6203E
uses an adaptive on-time mode control which provides a
very fast transient response with no external components.
The RT6203E operates from 4.5V to 18V VIN input. After
the initial power-up, the output voltage can be changed by
codes sent into the IC via an I2C compatible VID control
bus. There are special codes which can be used to program
current limit level and thermal shutdown level. Shutdown
and startup can be also programmed by special codes.
The device also features an internal soft-start time. Output
voltage is adjustable by VID code setting. VOUT range is
between 0.6V to 1.62V
