US3706 Datasheet (Unisonic Technologies) - CURRENT MODE PWM POWER SWITCH

US3706, CURRENT MODE PWM POWER SWITCH

The UTC US3706 combines a dedicated current mode PWM controller with a high voltage power MOSFET.

Low VDD startup current make the power reliable on startup design and a large value resistor could be used in the startup circuit to minimize the standby power.

At no load condition, the IC operates in
