UCS1603S Datasheet | Unisonic Technologies

DESCRIPTION The UTC UCS1603S is an integrated PWM controller and Power MOSFET specifically designed for switching operation with minimal external ponents. The UTC UCS1603S is designed to provide several special enhancements to satisfy the needs, for example, Power-Saving mode for low standby power, Frequency Hopping , Constant Output Power Limiting , Slope pensation ,Over Current Protection (OCP), Over Voltage Protection (OVP), Over Load Protection (OLP), Under Voltage Lock Out (UVLO), Over Temperature Protection (OTP), etc. IC will be shutdown or can auto-restart in situations. DIP-8 - FEATURE - Internal Power MOSFET (600V) - Programming Gate Driver Capability - Frequency hopping for Improved EMI Performance. - Lower than 30m W Standby Power Design - Linearly decreasing frequency to 20~35KHz during light load - Internal Soft start - Internal Slope pensation - Constant Power Limiting for universal AC input Range - ORDERING INFORMATION Ordering Number Lead Free Halogen Free UCS1603SL-D08-T UCS1603SG-D08-T - Gate Output Maximum Voltage Clamp(16V) - Over temperature protection - Over load protection - Over voltage protection - Leading edge blanking - Cycle-by-Cycle current limiting - Under Voltage Lock Out Package DIP-8 Packing Tube - MARKING .unisonic..tw Copyright © 2022 Unisonic Technologies Co., Ltd 1 of 7 QW-R103-116.E - PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT - PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME VCC-G VCC FB CS DRAIN DRAIN GND GND Supply voltage Supply voltage Feedback Current sense input Power MOSFET drain Power MOSFET drain Ground Ground - BLOCK DIAGRAM DESCRIPTION Notes: OLP (Over Load Protection) OVP (Over Voltage Protection) OTP (Over Temperature Protection) OCP (Over Current Protection) UVLO (Under Voltage Latch-Out) LEB (Led Edge...
