General Description

The RTQ2102A-QA is a full featured 6V, 1.5A, Advanced

Constant-On-Time (ACOT) synchronous step-down

converter with two integrated MOSFETs. The advanced

COT operation allows transient responses to be optimized

over a wide range of loads, and output capacitors to

efficiently reduce external component count. The

RTQ2102A-QA provides up to 2.7MHz switching frequency

to minimize the size of output inductor and capacitors.

The RTQ2102A-QA is available in the WDFN-8L 3x3

package.
