US3706 - CURRENT MODE PWM POWER SWITCH

Datasheet Summary

Description

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.

UNISONIC TECHNOLOGIES CO., LTD US3706 Preliminary CURRENT MODE PWM POWER SWITCH CMOS IC  DESCRIPTION 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 power-saving mode for lower standby power, decreasing frequency for Higher conversion efficiency at light load condition. The UTC US3706 offers complete protection coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), over temperature protection (OTP), over voltage protection and VDD under voltage lockout (UVLO).
