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
