US3706 Description

The UTC US3706 bines 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 power-saving mode for lower standby power, decreasing frequency for Higher conversion efficiency at light load condition.
