General Description
The RT8011/A is a high efficiency synchronous, step-down
DC/DC converter. Its input voltage range is from
2.6V to
5.5V and provides an adjustable regulated output voltage
from 0.8V to 5V while delivering up to 2A of output current.
The internal sy
nchronous low on-resistance power
switches increase efficiency and eliminate the need for
an external Schottky diode. Switching frequency is set
by an external resistor or can be synchronized to an
external clock. 100% duty cycle provides low dropout
operation extending battery life in portable systems.
Current mode operation with external compensation
allows the transient response to be optimized over a wide
range of loads and outpu
t capacitors.
RT8011/A operation in forced continuous PWM
Mode which
minimizes ripple voltage and reduces the noise and RF
interference.
100% duty cycle in Low Dropout Operation further
maximize battery life.
Note :
RichTek Pb-free and Green products are :
`
RoHS compliant and compatible with the current require-
ments of IPC/JEDEC J-STD-020.
`
Suitable for use in SnPb or Pb-free soldering processes.
`
100% matte tin (Sn) plating.
