Non-Isolated Auxiliary Power Supply up to 20W

In a number of applications the reference of the secondary circuit is connected to the same reference as the primary – the AC mains. In such cases, an off-line non-isolated auxiliary power supply can be used to provide a regulated DC voltage using an inductor or low-cost transformer – with simplified isolation – as an energy transfer element by modulating the power supply’s duty-cycle.

A buck – step-down – topology can be used to generate a positive output with respect to the common terminal and a buck-boost – or step-down/up – when the output voltage needs to be negative. A non-isolated fly-back converter is the alternative when a higher output power is required.

We offer a range of integrated – actually a power MOSFET, PWM controller and protection circuitry in a single package – high-voltage converters providing extremely low stand-by power, high – 800 and 900V – breakdown voltages and a range of protection features to help maximize efficiency and enhance reliability of power supplies.

In addition, we provide a comprehensive set of hardware and software evaluation and development tools as well as reference designs to enable a fast time to market.
