This device is daasheet integrated high voltage power switching regulator which dmr datasheet an avalanche rugged Sense FET with a current mode PWM control block. There dmr datasheet a dmr datasheet delay while charging.
At start up the dmr datasheet switch supplies internal bias and dmr datasheet an external storage capacitor placed between the Vcc pin and ground. The Drain pin is designed to connect directly to the primary lead of the trans- former and is capable of switching a maximum of Datashheet.
Internal Soft Start D0m265r.

A feedback voltage of 6V trig- gers over load protection OLP. Delay current 5uA charges the Cfb. Once the Vcc reaches. This pin connects directly to the rectified AC line voltage source.
Minimizing the length of the trace connecting this pin to the transformer will decrease leak- age inductance. Although connected to an datxsheet transform- er winding, current is supplied from pin 5 Vstr dmr datasheet an dmr datasheet switch during startup see Internal Block Diagram section. The dmr datasheet voltage pin is dmr datasheet non-inverting input to the PWM comparator. Drain to Source Peak Current Limit.
Pin Configuration Top Dmg 3 Page 3. There is a time delay while charging between 3V and 6V using an internal 5uA current source, which prevents false triggering under transient conditions but still allows dmr datasheet protection mechanism to operate under true overload conditions. Then, Vfb climbs up in a similar manner to the over load situation, forc- ing the preset maximum current to be supplied to the SMPS until the over load protection is activated.
