AX3704
can operate with input voltage from 2.5V to 5.5V and provide output range from 0.6V to
input level, thanks to its 100% duty cycle operation. The constant on time control sc heme
simplifies loop compensation and offers excellent load transient response.
AX3704
consumes extremely low 15µA quiescent current hence achieves superior light load
efficiency. AX3704 is a 1.5MHz, 4A constant on time (COT) controlled syn chronous step do wn
converter. The high gain error amplifier in the control loop provides excellent load and line
regulation. Proprietary adaptive on time helps AX3704 to achieve nearly constant switching
frequency across load range. AX3704 has cycle by cycle current limit and hiccup mode to protect
over load or short circuit fault conditions.
AX3704
is available in low profile 10 leads DFN 3mm x 3mm packages.
