DC-DC regulator reference style for vey high temperatures

Cissoid is supplying a reference style and evaluation kit for a DC-DC converter suitable for operation from -55°C as much as +225°C.

The reference design, referred to as Fuji, is made around the supplier’s CHT-MAGMA PWM controller IC. It implements a non-isolated discontinuous manage mode (DCM) flyback topology with triple output.

It’s going to commonly be utilised as a point-of-load generating locally 3 normal voltages from a single energy supply bus that will range from +12V to +28V.

The output voltage of the evaluation kit are +5V; +3.3V and +1.8V. The reference design might be modified to accommodate distinct voltage demands.?Default switching frequency is set to 100kHz and can be modified as much as 500kHz.

The Flyback regulation loop is set around the +5V output. Depending on the load conditions and around the regulation requirements on the application, the design and style can assistance two more built-in linear regulators that create the two lowest voltages.

The evaluation kit that involves a demonstration board, application note using the electrical schematic and bill of components.
