Power System Design (PSD) provides power solutions to its customers through AC-DC converters, offline switchers, and other PMIC products. The ACT510US-T is the latest addition to this comprehensive lineup of power solutions. With its integrated 12A, 200V switching MOSFETs, it enables high-efficiency AC-DC converting solutions for a range of applications.

The ACT510US-T is a state-of-the-art buck integrated circuit (IC) converter optimized for both high efficiency and cost. It can operate in either continuous conduction mode (CCM) or discontinuous conduction mode (DCM), depending on the system\'s requirements. It also has over-current protection and over-temperature protection integrated on-chip. The ACT510US-T\'s high performance and versatile features make it ideal for a variety of AC-DC converting solutions.

The ACT510US-T has a simple and efficient working principle. In CCM operation, the MOSFETs operate in series-connected buck topology. The upper MOSFET is always on while the lower MOSFET is driven by the synchronous rectifier controller (SRC). By driving the lower MOSFET on and off, the ACT510US-T generates a waveform which is averagely regulated by a feedback loop. This waveform is then rectified and filtered to generate a DC output voltage.

In DCM operation, the ACT510US-T operates in a half-bridge topology. The lower MOSFET is always on, while the upper MOSFET is driven by the SRC. The SRC turns the upper MOSFET on periodically to generate a waveform which is then averagely regulated by a feedback loop. The waveform is then rectified and filtered to generate a DC output voltage.

The ACT510US-T is an ideal choice for telecom and industrial power supplies, switched mode power sources, and other applications that require a high efficiency off-line switching AC-DC converter.

The ACT510US-T features a wide 6-75V input voltage range and features a voltage mode control loop with compensation. The wide operating temperature range of -40C to +125C makes it suitable for both industrial and outdoor applications. It also features over-voltage protection, over-temperature protection, and over-current protection, making it one of the safest and most reliable AC-DC converters on the market.

The ACT510US-T is an advanced, high-efficiency AC-DC converter optimized for both cost and performance. It features integrated 12A, 200V switching MOSFETs, allowing it to operate in either CCM or DCM modes. With its wide input voltage range, extended operating temperature range, and integrated safety features, it is the perfect choice for modern AC-DC conversion solutions.
