DESCRIPTION
A7442A is a High Efficiency, Dual Outputs Synchronous DC-DC Buck Converters with CV/CC modes, which can output up to 21 W in a wide range input from 6 V to 36 V. A7442A operates either in Constant Output Voltage (CV) mode or Constant Output Current (CC) mode and provides a separated current limit function for each channel. In order to achieve better EMI performance and comply with Apple’s MFi standard, the switching frequency was fixed at 130 kHz. A7442A is capable to operate in CC mode down to 3 V output voltage to protect the soft-short condition that is from the over current of the portable device
Other features including output Over Voltage Protection (OVP), Soft-start, hiccup mode output Under Voltage Protection (UVP), thermal shutdown (TSD), input UVLO. The hiccup mode output UVP can reduce the average input current to 50 mA.
The A7442A is available in PSOP8 package.
