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.
