A6059H,Off-Line PWM Controller with Integrated Power MOSFET, 100kHz,650V,17W, 8-DIP

The A6059H - DIP is an advanced off-line PWM controller with an integrated power MOSFET, designed for efficient power supply systems. This IC operates in a PWM mode for normal operation and switches to burst mode during light load conditions, reducing power consumption significantly. The device is highly efficient, delivering up to 17W of output power in adapter designs and up to 30W in open-frame designs at 230VAC input. Packaged in an 8-DIP form factor, the A6059H is ideal for use in applications such as low-power AC/DC adapters, auxiliary power supplies, and OA/AV equipment.

Its built-in protections, including Overcurrent Protection (OCP), Overload Protection (OLP), Overvoltage Protection (OVP), and Thermal Shutdown (TSD), ensure reliable and robust operation, even in harsh environments. The random switching function and slope compensation enhance performance and prevent EMI issues, while its audible noise suppression function makes it suitable for noise-sensitive applications. The device also features Brown-In/Brown-Out detection, adding further reliability to the system.

With its low standby power (less than 25mW) and automatic switching between modes, the A6059H ensures both energy savings and high-performance output, making it the optimal choice for various industrial and consumer electronics power supply designs.
