US3702

UNISONIC TECHNOLOGIES CO., LTD US3702 Preliminary LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE CURRENT MODE POWER SWITCH WITH ZERO CURRENT DETECTION  DESCRIPTION The UTC US3702 is an integrated PWM controller and SenseFET specifically designed for switching operation with minimal external components. The UTC US3702 is designed to provide several special enhancements to satisfy the needs, for example, Power-Saving mode for low standby power (<0.3W), Frequency Hopping , Constant Output Power Limiting , Slope Compensation ,Over Current Protection (OCP), Over Voltage Protection (OVP), Over Load Protection (OLP), Under Voltage Lock Out (UVLO), Short Circuit Protection (SCP) , Over Temperature Protection (OTP) etc. IC will be shutdown or can auto-restart in situations.  FEATURE * Internal high voltage SenseFET(700V) * Frequency hopping for Improved EMI performance. * Lower than 0.3W standby power design * Linearly decreasing frequency to 26KHz during light load * Internal soft start * Internal slope compensation * Constant power limiting for universal AC input range * Gate output maximum voltage clamp(15V) * Over temperature protection * Overload protection * Over voltage protection * Leading edge blanking * Cycle-by-cycle current limiting * Under voltage lock out * Short circuit protection  ORDERING INFORMATION Ordering Number Lead Free Halogen Free US3702L-D08-T US3702G-D08-T DIP-8 Package DIP-8 Packing Tube US3702L-D08-T (1)Packing Type (2)Package Type (3)Gre...
