General Description
The AP2965 is a High Efficiency Synchronous DC-DC Buck Converters with CV/CC modes, which can output up to 4.2 A in a wide input range from 6V to 36V. The AP2965 operates either in CV(Constant Voltage) mode or CC(Constant Current)mode. With the CV/CC mode, adjustable current limit and output voltage, the AP2965 is particularly suitable for QC 2.0/3.0(12V/1.5A, 9V/2A and 5V/3A), Type-C PD(5V/3A)and Apple portable device(5 V/2.4A) 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. AP2965 is capable to operate in CC mode down to 3V output voltage to protect the soft-short condition that is from the over current of the portable device. A discharge circuitry is integrated to quickly and reliably discharge output capacitors to avoid the faulty voltage delivery in case of output over voltage and ensure safe operation for QC 2.0/3.0 application. The hiccup mode output Under Voltage Protection(UVP) can reduce the average input current to 50mA. Features such as output cord voltage drop compensation and low voltage drop operation is especially suitable for car charger. AP2965 is available in S08-EP package which is beneficial for compact solution as well as thermal dissipation.
