RTKA210030DR0000BU
The RTKA210030DR0000BU demonstration board
(shown in
Figure 2
and
RTKA210030DR0000BU. Capable of delivering up to
3A of continuous current, the
compact, synchronous step-down, non-isolated
complete power supply that is optimized for
space-constrained applications. The
RTKA210030DR0000BU is based on a peak current
mode PWM control scheme that provides a fast
transient response and excellent loop stability. The
switching frequency is programmable from 500kHz to
4MHz with either the external resistor or
synchronization to an external clock through the
SYNC pin.
The RTKA210030DR0000BU demonstration board is
a 1×1 inch 4-layer FR4 board with 2oz. copper on
external layers and 1oz. copper on internal layers. It is
optimized to minimize the complete power module
solution size. Operating from a single 2.7V to 5.5V
input power rail, the RTKA210030DR0000BU
demonstration board offers adjustable output voltages
down to 0.6V, up to 95% efficiency, and better than
±1.5% accuracy over line, load, and temperature. A
dedicated enable pin and power-good flag allow for
easy system power rails sequencing.
By default, the board is set to a 1.8V output voltage
with a 2MHz switching frequency.

    5. To enable external frequency synchronization, remove the pull-up resistor R of the SYNC pin and connect the external clock to J3.2 (SYNC). To ensure proper operation, Renesas recommends that the external SYNC frequency is within ±25% of the switching frequency set by R at the FS pin.
