ACT4525YH-T Product Details

Qorvo's ACT4525YH-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.

ACT4525YH-T has separated output current limits for dual port Cigarette Lighter Adapter (CLA) applications. With the separated current limits, the CLA can meet Apple's MFi standard.

The product provides up to 3.5 A output current at 125 kHz switching frequency. ACT4525YH-T builds in USB auto-detect algorithms to recognize Apple, Samsung, and BC1.2 devices to ensure maximum charge current to attached devices. ACT4525YH-T utilizes an adaptive drive technique to achieve good EMI performance while maintaining > 90% efficiency at full load for mini-size CLA designs. ACT4525YH-T also has built-in output short circuit protection with hiccup mode. The average output current is reduced to below 6 mA when output is shorted to ground. Other features include output over-voltage protection and thermal shutdown.

ACT4525YH-T is available in a SOP-8EP package and requires very few external devices for operation.
