UPS602
LINEAR INTEGRATED CIRCUIT
HIGH PERFORMANCE
CURRENT MODE POWER
SWITCH
DESCRIPTION
The UTC UPS602 is designed to provide several special
enhancements to satisfy the needs: Power-Saving mode for low
standby power, Over Current Protection (OCP), Over Voltage
Protection (OVP), Over Load Protection (OLP), UVLO, Over
Temperature Protection (OTP) etc protection features. IC will be
shutdown when either protection arise and can auto-restart.
DIP-8

* Fixed switching frequency(Norm is 70kHz)
* Max duty cycle 70%
* Power-saving mode for low power
* Over temperature protection
* Overload protection
* Over voltage protection
* Leading edge blanking
* Soft start
