US1702

UNISONIC TECHNOLOGIES CO., LTD US1702 Preliminary LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE CURRENT MODE POWER SWITCH  DESCRIPTION The UTC US1702 is an integrated PWM controller and Power MOSFET specifically designed for current mode operation with minimal external components. The UTC US1702 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 , Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Lock Out (UVLO), and Over Temperature Protection (OTP) etc. IC will be shutdown or can auto-restart in certain situations.  FEATURE * Internal High Voltage Start-up Circuit * Internal 700V Power MOSFET * Lower than 0.3W Standby Power Design * Gate Output Maximum Voltage Clamp(15V) * Over temperature protection * Over voltage protection * Leading edge blanking * Cycle-by-Cycle current limiting * Under Voltage Lock Out  ORDERING INFORMATION Ordering Number Lead Free Halogen Free US1702L-D08-T US1702G-D08-T Package DIP-8 DIP-8 Packing Tube  MARKING www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 5 QW-R911-020.c US1702 Preliminary  PIN CONFIGURATION GND 1 GND 2 FB 3 VCC 4  PIN DESCRIPTION PIN NO. 1、2 3 4 5~8 PIN NAME GND FB VCC Drain Ground Feedback Supply voltage Power MOSFET drain  BLOCK DIAGRAM LINEAR INTEGRATED CIRCUIT 8 Drain 7 Drain 6 Drain 5 Drain DESCRIPTION Note...
