General Description

The RT8088A is a full featured 5.5V, 3A, Constant-On-

Time (COT) synchronous step-down converter with two

integrated MOSFETs. The current mode COT operation

with internal compensation allows the transient response

to be optimized over a wide range of loads and output

capacitors to efficiently reduce external component count.

The RT8088A provides up to 2.7MHz switching frequency

to minimize the size of output inductor and capacitors.

The output voltage is programmed through an I2C interface

capable of operating up to 400kHz.

The RT8088A is available in the WL-CSP-15B 1.31x2.11

(BSC) package.
