ACT4528YH-T Dettagli del prodotto

Qorvo's ACT4528YH-T is a wide input voltage, high efficiency step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode.

ACT4528YH-T has built-in QC2.0 decoding to provide 5.1 / 9.1 / 12.1 V outputs as requested by attached portable devices. It also supports Apple 2.4 A, Samsung and BC1.2 devices to charge at full current rate.

The product has accurate output current limits under constant current regulation to meet MFi specification. It can provide up to 3.0 A output current at 125 kHz switching frequency. ACT4528YH-T utilizes an adaptive drive technique to achieve good EMI performance while maintaining greater than 90% efficiency at full load for mini-size CLA designs. ACT4528YH-T also has output short circuit protection with hiccup mode. The average output current is reduced to below 6mA when output is shorted to ground. Other features include output over-voltage protection and thermal shutdown.

ACT4528YH-T is available in a SOP-8EP package and requires very few external components for operation.
