The AS3604-ZQFT provides up to four voltage output channels, supporting linear and nonlinear regulation, as well as integrated power-on reset circuit, system monitoring, brownout protection, and pre-charge/discharge circuits. The AS3604-ZQFT is widely used in different fields such as powering desktop computers, servers, and point-of-sale systems, providing power to communications devices, powering audio-video equipment and gaming consoles.

The AS3604-ZQFT is a highly accurate voltage regulator that is designed to achieve a tight voltage regulation of ±1%, with a minimum line regulation of 0.05%. It features a wide input voltage range of 200V to 400V and provides up to four adjustable outputs, with an adjustable voltage range of 0.8V to 6V, and an adjustable slew rate of up to 800 mV/ms. In addition, the AS3604-ZQFT can support both linear and nonlinear regulation and offers a wide frequency range of 50 kHZ to 1250 kHz. The AS3604-ZQFT also features an integrated power-on reset circuit and brownout protection to ensure reliable system startups, as well as an adjustable pre-charge/discharge circuit to compensate for current surges.

The AS3604-ZQFT is designed to deliver power efficiently, with a maximum input current of 5A, a maximum output current of 10A/port, and a maximum total output current of 30A. The device\'s power conversion efficiency is up to 97%. It can be equipped with remote sense, temperature monitor, and compensation functions to achieve excellent load- and line-regulation. The AS3604-ZQFT has a maximum power dissipated of 8W, a junction temperature range of -40°C to +85°C, and an operating temperature range of -20°C to +65°C.

The AS3604-ZQFT features a high level of system safety and protection, including under-voltage lockout (UVLO), over-voltage lockout (OVLO), over-current protection (OCP), and output short-circuit protection (SCP). The device has a thermal protection circuit, which will shut down the system and put it into a safe state if the device\'s die temperature exceeds the specified threshold. It also features a voltage ramp-up/down control circuit, which limits surge currents and prevents inrush currents when turning the system on and off.

The AS3604-ZQFT is an ideal solution for a wide range of power management applications, and offers a high level of system safety, protection, efficiency and reliability. Its flexibility, precision and features make it suitable for powering a variety of electronic products and systems.
