... Sense FET source terminal on primary side and internal control ground. Positive supply voltage input. Although connected to an auxiliary transform- er winding, current is supplied from pin 5 (Vstr) via an internal switch during startup (see Internal Block Diagram section not until Vcc reaches the UVLO upper threshold (12V) that the internal start-up switch opens and de- vice power is supplied via the auxiliary transformer winding ...

... Vstr pin had an external resistor to the DC input voltage line. In this generation the startup resistor is replaced by an internal high voltage current source and a switch that shuts off when 15ms goes by after the supply voltage, Vcc, gets above 12V. The source turns back on if Vcc drops below 8V. ...

... In general, Vcc is proportional to the output volt- age and the FPS uses Vcc instead of directly monitoring the output voltage resulting in termination of the switching operation. In order to avoid undesired activation of OVP during normal opera- tion, Vcc should be properly designed to be below 19V. PWM ...

... V V Waveform Vfb t 7. Frequency Modulation : Modulating the switching fre- quency of a switched power supply can reduce EMI. Fre- quency modulation can reduce EMI by spreading the energy over a wider frequency range than the bandwidth measured voltage drops below by the EMI test equipment. The amount of EMI reduction is directly related to the depth of the reference frequency ...

... Application Tips 1. Methods of Reducing Audible Noise Switching mode power converters have electronic and magnetic components, which generate audible noises when the operating frequency is in the range of 20~20,000 Hz. Even though they operate above 20 kHz, they can make noise depending on the load condition. Designers can employ several methods to reduce these noises ...
