Description:

DC-DC CONVERTER/BUCK

Features

* such as output cord voltage drop compensation and low voltage drop operation is especially suitable for car charger. FEATURES
* Wide Input Supply Voltage Range of 6V ~ 40V
* Up to 4.2 A Output Current
* Up to 95 % Efficiency
* 130kHz Fixed Switching Frequency
* Internal Soft-sta

Applications

* The output voltage and CC limit can be programed through the FB, CSP and CSN pins respectively. In order to achieve better EMI performance and comply with Apple’s MFi standard, the switching frequency was fixed at 130kHz. A7442 is capable to operate in CC mode down to 3V output voltage to protect t
