Normally limited by internal circuitry. The products and applications illustrated herein transformer construction and circuits external to. This supply is used in appliances where certain standby functions e.

Primary side circuit common and reference point. The shunt regulator voltage is accurately derived from the temperature compensated bandgap reference. To avoid triggering the current limit in normal operation, the 30 second hormone fix pdf the drain current waveform should stay within the envelope shown. Provides internal bias current during start-up operation via an internal switched highvoltage current source. The gate drive current is trimmed for improved accuracy.

Trimming of the current reference improves the frequency accuracy. All terminals are solder plated. The products and applications illustrated herein transformer construction.

Typical Flyback Application. The base current from the curve tracer should not exceed mA. For this application the input rectifiers and input filter are sized for the main supply and are not shown. We use Cookies to give you best experience on our website. Remember me Forgot password?

Controlling dimensions are inches. Major Ratings and Characteristics.

Learn how we and our ad partner Google, collect and use data. Autorestart continues to cycle until output voltage regulation is again achieved. Hysteretic regulation is used for initial start-up and overload operation. The maximum voltage from the curve tracer must be limited to V under all conditions. As the control current increases, the duty cycle decreases.
