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.
