The RT5759 is a high-performance, synchronous stepdown
DC-DC converter that can deliver up to 9A output
current from a 3V to 6.5V input supply. The output voltage
can be programmable from 0.6V to 1.5V with I2C controlled
7-Bits VID.
The device integrates low RDS(ON) power MOSFETs,
accurate 0.6V reference and an integrated diode of
bootstrap circuit to offer a very compact solution.
The RT5759 adopts Advanced Constant On-Time (ACOTTM)
control architecture that provides ultrafast transient
response and further reduce the external-component
count. In steady states, the ACOTTM operates in nearly
constant switching frequency over line, load and output
voltage ranges and makes the EMI filter design easier.
The RT5759 offers automatic PSM that maintains high
efficiency during light load operation. The RT5759 can also
operate in Forced-CCM through I2C setting that helps meet
tight voltage regulation accuracy requirements.资料下载
